Funny you should say. I started watching his Python tutorials around 6 years ago. It radically improved my efficiency at work by writing a bot that basically automated about 60 percent of my job. My boss never did know how I did my job much faster than my coworkers. Then I got a job doing similar work for about twice the pay based on those skills.

Thank you Derek! I was preparating myself for aerospace engineering (even though I still have a long way to university). I made a playlist with some videos to help me preparate myself, and made it public, just so you know. Thank you a lot to let me learn all this content!
Wow that is insane because I'm doing the same thing!! Preparing myself for university as well, hoping I'll be ready for it in a year. Good luck dude I'll be checking out your playlist!
Simple mistake at 5:55, but I'd like to address it: multiplying x by x gives you x^2. You would only get 2x if you combined like terms such as x + x. Other than that, great video! Very helpful!
Ooh exactly legit fr irl imho @op. That is one of if not my favourite things about yt is it is like the internet fwiw ftw evne., full an fileld with so much abundance of learning/teaching video of many skills and a vast array of knowledge among the plethora of music videos/ytp's etc. That is ftw fr. My fav yt channels I feel teach me somewat in some way or another. Or that at least I can and have a desire for learning something fwiw I can take away from each video now.
Wow, your programming videos really helped me a lot over the years and now maths! Thank you very much! I am of course subscribed with notifications turned on and thumbs up!
Well Done Sir! I had to start over and set aside my Old notes. Taking new Notes now based on this Video. I have College in the Fall and Need to Test outta some Math Classes.... This is my before watching the whole Video....

Beautiful! I've got my International Advanced Level (IAL) exam this year's May/June and your videos are helping me a lot. Looking forward to linear algebra and calculus videos!
I am so interested in math, that I even want to be a mathematician when I grow up!!! I didn't know where to start, but now I found this video, it helped me so much and gave me a great jump start. THANK YOU FOR MAKING THIS VIDEO!!!
27:00 The worst thing you could do in Algebra is to memorize formulas without understanding, if you can understand the math you can just derive them, so they make sense to you and therefore never forget them. The formula shown in the video for example is derived from the Pythagoras theorem, so no need to memorize it. 37:00 in this case for example we could explain why we are even to do this to begin with adding 2 linear equatuons, instead of trying to memorize some seemingly arbitrary procedure.
Professor Derek Banas, there are many errors in this video on Learning Algebra One and Two.Some of the viewers have found and corrected critical errors in this lengthy video. At the 56:23 minute mark in the video, you have 3x - 1 followed by x equal to negative one third. At the 1:39:35 minute mark in the video, when you factor 2 x cube minus 6 x squared minus 5 x plus 15 , you have ( 2x squared minus 5)( x minus 3x). For this problem, the correct solution is (2 x squared minus 5)( x minus 3). At the 1:43:57 minute mark in the video, there is an error with the remainder Professor Banas, please correct all the errors in this lengthy video.
Please keep doing these videos on math all the way through like you said. You are very easy to understand. That’s not very common. I’m reading a lot of books Tesla. Also stuff on magnetic fields. I can always understand the mechanics, but when the books get into the math, it gets real confusing and I believe your courses would really really help me. Thank you so much for doing this.
Just took my first universty course in linear algebra, i figured out i had some problems with basic algebra. Amazing Refresh. Thanks alot from Israel !
Hi Derk, Thanks for the math brush up, needed it to help out my kids. I follow your channel from 2008, amazing the amount of knowledge you poses. Keep it up mate.
Hello, I just have a question about 23:49 and if b = 1/4 or is added for 7/4 as when I attempted it it seemed liked -3/4 I am just reviewing for a new algebra two course I’m take but your videos are super helpful
i'm a 9th grader entering algebra 1 all of my previous math teachers have been horrible and never taught me correctly thank you for this video very appreciated.
Thank you. I need to reach calc and then partial differential equations fast, for ai. thank you for this video. You have so many courses on your channel honestly thats just mind blowing . I am just here to show my thanks and appreciation 😊. Hope you are doing well
Since he was going so fast, he didn't repeat that the original question was to find a line *parallel* to x - 4y = 1 that intersects a point of (-3, 1). That means he had to, first, find "m", the slope of his line, which will be the same for the parallel line, and then find "b", the offset up or down the y-axis for the parallel line. So with y = (1/4)x - 1/4, he had solved for "m", and then he could solve for "b" by plugging in his known values into y = mx + b. So taking y = mx + b, knowing that the slope is 1/4, and this parallel line intersects (-3 ,1), you would start with 1 = (1/4)(-3) + b. Now, he skipped a few steps with writing this out and instead just started with b = (4/4) + (3/4), to get b = 7/4, which without referring back to the original question, looks and sounds confusing, but it means the parallel line is y = 1/4x + 7/4. I think he zipped just a little too fast there. This is a crash course mostly for people just refreshing themselves, but teachers should avoid doing steps in their heads while instructing.
I would love to have all your notes on paper so I can 'play' with them anywhere at anytime when I need to relax! I can't continue watching now as it is 11.47pm, 18.8.24, and I've just had a week of very late nights at Broadstairs Folk Week BUT I really wish I'd found you at 6 o'clock this morning so I could have played with algebra all day! Jeni
Thank you so much for this. I am going back to college and have to take Precalc 2 and it has been 4 years since I took Precalc 1 so I am very rusty. Hopefully 2 weeks can be enough time to prep Update: I got a B in Precalc 2!
If I could request anything, it’d be to always show your work for us even if you think it’s a given because it could prevent becoming lost while trying to follow the course @ 12:23 it threw me off because math is not my strong suit, hence why I’m watching this, and I couldn’t figure out how you got -3x after subtracting 4 from both sides, I was like “no way he subtracted from 10 because that’d be 6 not -3x” I stopped right there and kept rewinding it over and over because I figured I missed something until I just let it play n realized you were just repeating the result and writing the equation as a whole🤣🤣 Just allowing it to play itself out was a huge relief cuz I was near boutta cry thinkin i can’t even comprehend a simple algebraic equation 😭🤣🤣 anxiety and panic definitely got its beating in today😂 Overall I love this channel 😅
34:11 you forgot to flip the > when multiply by minus so its x < 6 and not x > 6 it was easier to just leave the 2 in his place and move the -1/3 to the other side
Mistake at about 5:52 .... x times x isn't 2x is't x^2 ... at 1:10:10 your second step is technically not equal to the starting problem as he suggests it is, so even though he gets the correct final answer it's confusing....at 1:15:30 the second rule is wrong, the 2 should be an a..... at 1:32:25 he says 2 and 6 work and then proceeds to write a 2 and an 8, so it should be (x+2)(x+6).... I see now at 1:34:45 he corrected that last one after someone commented..... at 1:37:20 he says 2^2 when he meant to say 2^3. However he fixes it in the next step and gets the right answer...... at 1:39:00 he says (x-3x) when he meant (x-3)... then he gets the final answer wrong as he uses (x-3x) again... which is obviously wrong as it simplifies to -2x but he's clearly trying to get this done as fast as possible and not catching these things... and I think fatigue is setting in lol..... 2:16:40 I think this explanation of what makes the function even or odd is pretty confusing, especially since you said -x^2+2 is equal to (-x)^2+2.... this actually isn't true because in the first one only the x is squared but in the 2nd one the square is applied to the negative sign.... he makes a similar mistake in his explanation for the odd function that follows...and to say substitute a-x for your function isn't really helpful... didn't even explain what a is...honestly I didn't understand that sentence at all... I think maybe he meant to say that f(x) = f(-x) which would be the true definition of what makes a function even...but then he did say that shortly after.
hello there, you seem to know what you're talking about so i was just wondering at 56:54 (finished problem) i know that he shouldn't have dropped the negative from the 3 at the beginning, but how did he get l x + 2 l = -2 from 3 l x + 2 l = -6? i have no clue how 4 was just suddenly added to the equation. do you think you could just work me through the entire problem?
Actually after looking it over again, I realized that he did it correctly and removed that part of my comment.... he still didn't explain it very well as he hasn't in a lot of this video as he's just trying to go through everything really fast and so he isn't covering a lot of the details..... but let me re-write his steps adding one more in the middle to help explain how he got his final answer: 9-3lx+2l = 15 -3lx+2l =6 (after subtracting 9 from both sides.... he did this step and the next one in one step) 3lx+2l = -6 (he divided each side by -1... he just saw that there was a negative sign that he'd prefer on the other side so he intuitively moved it to the other side... I wouldn't have done it this way but nothing wrong with it) lx+2l =-2 (he divided by 3 on both sides) From here you can see it's no solution.... of matter what you plug in for x, lx+2l can't equal a negative number... x+2 could be positive or negative but either way lx+2l can't be negative.... I don't know why he wrote x+2=-2 at the end.... it looks like he was starting to go through the next step that you would take if it was an abosolute value problem with a solution but then realized that it wasn't nesasarry and just stopped.
@ 18:14 why’d you choose to plug in y2 and x2 instead of y1 and x1? Does it matter which values you plug in for y=mx+b ? And how does 10/-3 become -10/3? And what’d you do to get b=-18 after 2=20+b ? I thought you have to divide 20 by 2??
Thank you so much. I am taking an electrical engineering career training high school class. The prerequisite is a minimum of a c in algebra. I was never good at algebra. This should hopefully help.
I'm happy I could help. This is basically one example for most anything you'll ever see in Algebra 1 and 2. If you can solve them on your own after watching this you'll get an A on every algebra test
@@derekbanas So if I can Solve the Algebra 2 Questions on my own after watching this, I'll be alright during tests? I'm a Sophomore in highschool taking it and I am really struggling with this. So if I do the problems by myself I'll pretty much know like 80% of Algebra 2?
Method 1) (- x= 6) equation is given Multiplying both sides by (-1) -1*-x= -1*6 Then x= -6 or Method 2) Let the equation be (- x= 6) If we multiply both sides with "MINUS" sign -(- x)= -(6) Then x= -6. Which one method is correct or both methods are correct Please help 🙏🙏
Thanks for much for this video I'm a junior developer and just finished your algebra video What other videos or topics are there that would be most beneficial to my in your opinion ?
Thank you for this video... One of the best video for mathematics... Totally high school basic but thoroughly explained... Please ping here your machine learning playlist.. unable to find..
I'm confused, at 23:32, you claim that we must set x = 0 to easily find the y intercept. That's not how I did it. I would substitute "y = mx + b" with the values in the given point and the slope that we had found. It gives the same answer, being 1.75, but I don't get how you did it.
Hello Mr. Banas, I hope this message finds you well. As a senior in high school preparing to start college this fall, I am planning to take college algebra and I was wondering if you know of any additional resources or tips that could help me prepare for the course. Thank you for the video!
I think two resources may help. The No-Nonsense Algebra books are good. I'd use them in combination with an app like Symbolab. Symbolab will take a picture of any problem and then explain step-by-step how to solve it. There are only so many different types of Algebra problems you will ever see. If you set them up and can solve all of the types you can solve them all. I did my best to provide one of any type in this video, but additional resources and problems always help.
Can someone help me? I’m stuck in minute 24:00 , I don’t get how he got 4/4 and 4/3?? I think I know how he got 4/4 but not sure on how he got 4/3, I really need help here
23:51 where do you pull the numbers for b? I was following along up until that point. Are you using the initial eq x-4y=1? Rewritten to -4y=-x+1 -> y= 1/4x -1/4 which is y= mx+b for that and then the new eq at least so far is y= 1/4x + b. My thoughts are kinda scattered so this is probably not being worded too properly I’m just trying to see where the 4/4+3/4 = 7/4 comes from
Okay I think the process of point slope form was just skipped? Y-y1 = m(x-x1) Y-1 = 1/4(x-(-3)) Y-1 = 1/4x + 3/4 Y = 1/4x + 3/4 + 1 Y = 1/4x + 3/4 + 4/4 Y = 1/4x + 3/4 + 4/4 Y = 1/4x + 7/4
Goodmorning, it seems you tend to knoe this stuff. Can I ask how to solve that particular equation from the start? I'm sorry I think I did get a bit lost after he start changing the position of -4y and the equal signs and things just went move on and on and I don't know anymore. Thank you.

Just allowing it to play itself out was a huge relief cuz I was near boutta cry thinkin i can’t even comprehend a simple algebraic equation 😭🤣🤣 anxiety and panic definitely got its beating in today😂
Overall I love this channel 😅
34:11 you forgot to flip the > when multiply by minus so its x < 6 and not x > 6 it was easier to just leave the 2 in his place and move the -1/3 to the other side
I am enjoying these videos. Did you create the course on Matrices? I couldn't find it when I scrolled through all your videos
Algebra 2 summer school highschool course is kicking my ass. If this video doesnt work honestly i give up.
Did it work?😭
@nah7282 no, i cheated the rest of the semester and passed with a d-
1:44:09 lifesaver in calc 2 partial fractions
Mistake at about 5:52 .... x times x isn't 2x is't x^2 ... at 1:10:10 your second step is technically not equal to the starting problem as he suggests it is, so even though he gets the correct final answer it's confusing....at 1:15:30 the second rule is wrong, the 2 should be an a..... at 1:32:25 he says 2 and 6 work and then proceeds to write a 2 and an 8, so it should be (x+2)(x+6).... I see now at 1:34:45 he corrected that last one after someone commented..... at 1:37:20 he says 2^2 when he meant to say 2^3. However he fixes it in the next step and gets the right answer...... at 1:39:00 he says (x-3x) when he meant (x-3)... then he gets the final answer wrong as he uses (x-3x) again... which is obviously wrong as it simplifies to -2x but he's clearly trying to get this done as fast as possible and not catching these things... and I think fatigue is setting in lol..... 2:16:40 I think this explanation of what makes the function even or odd is pretty confusing, especially since you said -x^2+2 is equal to (-x)^2+2.... this actually isn't true because in the first one only the x is squared but in the 2nd one the square is applied to the negative sign.... he makes a similar mistake in his explanation for the odd function that follows...and to say substitute a-x for your function isn't really helpful... didn't even explain what a is...honestly I didn't understand that sentence at all... I think maybe he meant to say that f(x) = f(-x) which would be the true definition of what makes a function even...but then he did say that shortly after.
hello there, you seem to know what you're talking about so i was just wondering at 56:54 (finished problem) i know that he shouldn't have dropped the negative from the 3 at the beginning, but how did he get l x + 2 l = -2 from 3 l x + 2 l = -6? i have no clue how 4 was just suddenly added to the equation. do you think you could just work me through the entire problem?
Actually after looking it over again, I realized that he did it correctly and removed that part of my comment.... he still didn't explain it very well as he hasn't in a lot of this video as he's just trying to go through everything really fast and so he isn't covering a lot of the details..... but let me re-write his steps adding one more in the middle to help explain how he got his final answer:
9-3lx+2l = 15
-3lx+2l =6 (after subtracting 9 from both sides.... he did this step and the next one in one step)
3lx+2l = -6 (he divided each side by -1... he just saw that there was a negative sign that he'd prefer on the other side so he intuitively moved it to the other side... I wouldn't have done it this way but nothing wrong with it)
lx+2l =-2 (he divided by 3 on both sides)
From here you can see it's no solution.... of matter what you plug in for x, lx+2l can't equal a negative number... x+2 could be positive or negative but either way lx+2l can't be negative.... I don't know why he wrote x+2=-2 at the end.... it looks like he was starting to go through the next step that you would take if it was an abosolute value problem with a solution but then realized that it wasn't nesasarry and just stopped.
@@Josh-zt8dw wow thanks so much! appreciate it!
for 5:52 x+x=2x would be a better fit I guess
24:08
I am little bit confused. Shouldn’t the y-intercept be -1/4 or am I missing something?
yeah i have the same problem currently cause im wondering where he got those numbers from
it is 1 and it has /1 so you muliply it by 4 so it becomes 4/4 to then add to the 3/4 so it will equall to = 7/4. i guess that's how it is
@ 18:14 why’d you choose to plug in y2 and x2 instead of y1 and x1? Does it matter which values you plug in for y=mx+b ?
And how does 10/-3 become -10/3?
And what’d you do to get b=-18 after 2=20+b ? I thought you have to divide 20 by 2??
This is a great video to remember all the skills I had previously forgotten.
My math teacher unfortunately doesn’t teach math well but this has helped me so much! Thank you.
Hi again mate, i already follow your "learn algebra" series, should i watch this video after I finish the series? or are these the same lessons?
These are not the same lessons, but it is way more intense and fast. I recommend following the slower multipart version
6:06 thats a mistake, a variable multiplied by a variable is a variable squared, not 2(var)
on 34:17 it's not 6 < x but 6 > x because multiply or divide by negative number will flip the sign
example:
20 > -10
(-1) 20 > -10 (-1)
-20 < 10
wow man , this is the best revision of basics i could possibly hope for, +1 subcribeD :D
Thank you very much :)
I really needed this, just about to have an algebra1 exam and am feeling pretty lost
This helped so much! TYSM 🤪
Thank you so much. I am taking an electrical engineering career training high school class. The prerequisite is a minimum of a c in algebra. I was never good at algebra. This should hopefully help.
I'm happy I could help. This is basically one example for most anything you'll ever see in Algebra 1 and 2. If you can solve them on your own after watching this you'll get an A on every algebra test
@@derekbanas So if I can Solve the Algebra 2 Questions on my own after watching this, I'll be alright during tests? I'm a Sophomore in highschool taking it and I am really struggling with this. So if I do the problems by myself I'll pretty much know like 80% of Algebra 2?
I'm a grown man, probably old enough to be someone's grampa.
Even kid's algebra is a much needed refresher..
at 5:50 x multiplied by x would be equal to x raised to the power 2
This helps alot , THANK YOU SO MUCH !!!!
Method 1)
(- x= 6) equation is given
Multiplying both sides by (-1)
-1*-x= -1*6
Then x= -6
or
Method 2)
Let the equation be (- x= 6)
If we multiply both sides with "MINUS" sign -(- x)= -(6)
Then x= -6.
Which one method is correct or both methods are correct
Please help 🙏🙏
56:20 9-3 | x+2 | = 15 to -3| x+2 | = 6?
In 34:17, I know it's valid, but where does he get point (3,1) from? why didn't he use point (6,0)?
thank you! can’t wait for the calculus video
….
I worked out the problem and I don't see how you are getting b to equal 7/3 at minute mark 23:32. Can you explain in a little more detail? Thank you
as a 18 y old who dropped out of highschool im thankful i have the ability to still develop my education and thank you for providing that.
still need to work on my basics. wow. I got lot of climbing to do if im to follow this. im ready for the challenge... LETS GO!
Dude, I think you've saved my sophomore year.
Happy to help :)
how fast and efficiently you taught this was wild i completed the whole thing from scratch in 3 days lol.
hey guy, what do you think, this tutorial is enough to study about algebra 1 and 2, so can we now practice this more and move forward
@@gauravsonawane7554no, it’s just. Brief explain action for people that want a refresher mostly but wouldn’t recommend for learning.
God bless you, sir!
God bless you and your loved ones as well :)
Thank you this is really helpful.
Dude, absolute life savor.
Thanks for much for this video
I'm a junior developer and just finished your algebra video
What other videos or topics are there that would be most beneficial to my in your opinion ?
If you want to into Machine Leaning or Data scence then Trig, Pre calculus, calculus, linear algebra.
Thank you for this video...
One of the best video for mathematics... Totally high school basic but thoroughly explained... Please ping here your machine learning playlist.. unable to find..
Nice vid & dope shirt!!
@ 1 hour and 18 minutes roughly,
Factoring Trimials:
X^2 + 8x +12 = (x + 2) (x + 6)
You wrote:
(X + 2)(x + 8)
Sorry about the typo. I correct it a little later into the video
I'm confused, at 23:32, you claim that we must set x = 0 to easily find the y intercept.
That's not how I did it. I would substitute "y = mx + b" with the values in the given point and the slope that we had found. It gives the same answer, being 1.75, but I don't get how you did it.
thank you mr banas. very good video and this feels like im being tutored. way better teacher than my current algebra teacher haha
6:00 x times x is x squared not 2x
Hello Mr. Banas, I hope this message finds you well. As a senior in high school preparing to start college this fall, I am planning to take college algebra and I was wondering if you know of any additional resources or tips that could help me prepare for the course. Thank you for the video!
I think two resources may help. The No-Nonsense Algebra books are good. I'd use them in combination with an app like Symbolab. Symbolab will take a picture of any problem and then explain step-by-step how to solve it. There are only so many different types of Algebra problems you will ever see. If you set them up and can solve all of the types you can solve them all. I did my best to provide one of any type in this video, but additional resources and problems always help.
@@derekbanastysm!
Good day, Derek!🙏
Thank you :) I hope you have a good day as well
thank you very much for the video
Thank you so much m8 :D
Hi Derek how do you record your videos on iPad? thanks
I stream the screen using AirServer on Windows to OBS
good to know you also have a video for trigonometry
I want to learn more about calculus. I am still learning new things about pre - calculus
I’ll be covering calculus at some point this month
Can someone help me? I’m stuck in minute 24:00 , I don’t get how he got 4/4 and 4/3?? I think I know how he got 4/4 but not sure on how he got 4/3, I really need help here
divide the logarithm of sine
Is this based on a particular textbook or books, or from personal lecture notes?
23:51 where do you pull the numbers for b? I was following along up until that point. Are you using the initial eq x-4y=1? Rewritten to -4y=-x+1 -> y= 1/4x -1/4 which is y= mx+b for that and then the new eq at least so far is y= 1/4x + b. My thoughts are kinda scattered so this is probably not being worded too properly I’m just trying to see where the 4/4+3/4 = 7/4 comes from
Okay I think the process of point slope form was just skipped? Y-y1 = m(x-x1)
Y-1 = 1/4(x-(-3))
Y-1 = 1/4x + 3/4
Y = 1/4x + 3/4 + 1
Y = 1/4x + 3/4 + 4/4
Y = 1/4x + 3/4 + 4/4
Y = 1/4x + 7/4
Goodmorning, it seems you tend to knoe this stuff. Can I ask how to solve that particular equation from the start? I'm sorry I think I did get a bit lost after he start changing the position of -4y and the equal signs and things just went move on and on and I don't know anymore. Thank you.
At minute 24, where did you get 3/4 from?
😂 I'm having to freshen up my algebra to take a lineman assessment test and let's just say I feel pretty confident that I'm going to fail the assessment test......
You sir have the mathematical skills equivalent to Einstein and I have the mathematical skills equivalent to a potato. 🥔
It's 4am, i'm high af and last time i learned basic algebra was 6-7 years ago
