Well... my teacher, here in Brazil, refused to teach us Logarithms because "it was too hard to learn" (that's how it works here). So, I decided to learn on my own and I found this brilliant teacher. Thank you so much for this, this is so important for people like me who has to find alternatives to this system that doesn't care if we learn (even the basics) or not.
@@randomviewer1285 yeah, I guess so. I'm from BR as well, and only now I'm learning functions and logarithms on my own, even though I finished school in 2016. The public education is a joke, I'm glad there are videos like this on YT for ppl like me because I need to know this stuff for my engineer course.
@@BurningGreyX I'm brazilian as well, we have log on exams like ENEM (high school national exam) and college entrances but even studying in a particular school we don't get this explained really well here. my teacher is good but she doesn't have the time necessary to explain something in a good way, it feels rushed and sometimes we really can't understand it. I'm in my last year in high school and I also came looking for classes like this to try and learn these stuff on my own
Actually, here in Brazil, we do learn Log, the problem is if u are in a public or private school, because the public teaching is far worse than the private. But, if u are in a private, u don’t learn if u don’t want to. Ps: For the “Big foot” the Brazil never got close to be a socialist country, so stop spreading fake news. Ps2: srry for my English 🙃
Dear Mr. Eddie Woo, Coming form a Fifth-Year Medical Student who had at some point to revisit some of the mathematical concepts: You are the most talented teacher I've ever had!
Please keep on uploading your inspiring lectures for future generations to learn from your talented insights. Best Regards, Alaa I. Ismail
I’m an engineer in finance, I have been doing math all my life but only by myself, always reading books instead of listen to teacher. You are the reason why I was right, always had the feeling nobody really explain me the “REAL WHY”, you just keep doing this lesson after lesson. I have to tell you something : Thank you!
You can also say, how many time can you divide the result by the base until you get 1. So 3^4=81 and log3(81)=4 then 81/3=27 27/3=9 9/3=3 3/3=1 Four total steps so 4 is the answer. As for the log.sqrt3(27) you can first square the base and then work with 3 and then empower it So (sqrt3)^2=3 obviously and then divide 27 by 3 and then the answer by 3 and again so 27/3=9 9/3=3 3/3=1 So three times, 3^3, but 3 wasn’t the base. Rewrite 3 as in the base form (sqrt3)^2 and power that by your amount of steps (sqrt3^2)^3 that’ll be (sqrt3)^(2x3) or (sqrt3)^6 so answer is 6 Hope this will was clear enough and gave you another perspective on this :)
You are a great teacher, thank you very much for sharing it for free with the world! Greetings from Brazil, where education like yours is hard to find and expensive.
I'm have Masters degree in CS. I need to brush up Math skills for Algorithmic interviews and this helped a lot. Your teaching is amazing and simple. Subscribed. Keep going sir. Please/ More videos please.
He involves the class, it is a two way interaction. The wrong way to do it namely my experience with maths, is to sit there while the teacher yawns out a load of lines at you and you copy it down like a machine. He does not give the chance for students to idle because they are all participating in it together. This is a template example of the way a class should happen and one that is a perfect example thereof.
@@infinitesimotel That teaching style is pretty outdated imo. It had value when we didn't have the internet, information was valuable. Now information for basic topics is everywhere, the whole value in school is personal interaction.
@@MsJavaWolf It's true, you can learn a lot on the 'net. And the 1st thing everybody ought to learn is to be skeptical of everything they "learn" on the 'net. Also cream bun pointed out that Eddie's teaching style is *about* personal interaction, so I don't know what you're saying is outdated.
Just came to this video because I couldn't understand how logarithms worked, my teacher said "that's just how it is don't ask how or why". After watching this video, it all made sense. Eddie Woo you are a legend!
I wish I had a math professor like you in college. You take what in many cases are complex principles and make them easy to understand. I hope your students realize how very fortunate they are to learn mathematics from you. Keep up the great work Sir.
I remember try use logarithms at school...the explanation was if you want to get this number here, plug in this equation. I got the right answer by plugging in the algorithm, but learnt nothing as I didn't get what a log was. Great explanation.
I am coming back to the subject to help students but remember being taught how to use logarithmic tables to do calculations. The big advantage in the 16th century (when they were invented) was that you could convert multiplication problems into their log number add them together and then convert the answer back to denary. But there is another way where multiplication is made so easy that it is no more difficult than adding which is by using binary arithmetic which was what Liebniz used instead of logs. I think if we taught the history of maths students would get a greater understanding of how & why these things were developed. Logarithmic graphs enable one to see growth across a wide scale.
i like your teaching style, and i think your students are lucky to get math explained by you, but i really feel bad that there´s no new knowledge for me on your channel. do you think you will someday make videos on higher mathematical topics (eg complex calculus)?
check out professor Leonard.....RUclips sensation. teaches everything from algebra up through stats, calc 3, de, etc. The best math teacher I've ever watched. Also, go to to MIT Opencourseware.
I love your channel and your enthusiasm for math. When you make complicated concepts logical by tackling them slowly and making sure to have a complete understanding at each step, it shows me the true beauty of math.
so, due m personal issues, I skipped whole entire grade and so I could not learn what logarithms is, and this man explained in minutes. Thanks for doing it. This 5 year old video will help students even after years.
I have my math trial in 20 minutes. I was frantically doing some last minute revision and found this man. At least I understand how logs work now, so I shouldn’t fail those too badly.
Thanks a lot. You helped me realise something so big in my life. You helped me realise why I was losing my interest in maths..... The reason I was losing interest in maths is because I haven't learnt anything new is sooo long. These videos, reignited that passion. THANK YOU MR.WOO!!!
explaining an idea in layman language reveals a deep understanding of the concept, as the saying goes "the only way to learn math is to understand it" you are a pretty solid manifestation of that saying, thank you.
It is truly amazing to watch somebody so competent at their craft, they can easily teach others. I am so excited to learn what all that homework in my past actually meant. Although I'm shocked I ever passed any math class without much understanding of the concepts. Thank you sir, you are an inspiration.
So I just found his videos and I am in love with math now 😂 and I just keep on telling everybody how good he teaches repeatedly. I so want a teacher like him in real life.
Failed to learn in 1st year but learning something now about logarithms from this video . In economics calculus & logarithms is used for solving many problems . Continue with you to learn more . ☺
The best way to teach a class is to treat them all like they're morons. Love how he explains the simplest of things without assuming that something is general knowledge.
OMG thank you so much!!! this helped A LOT!!! You are by far the best teacher I have come across explaining this topic!! It was so CLEAR and sooooo easy to understand!!
The power function has two opposites; root and log, unlike add and multiply which both have one opposite each; minus and divide respectively. Because with power it matters which order they are in and with add and multiply it doesn't. 2+3 and 3+2 both equal 5, 2*3 and 3*2 both equal 6, but 2^3=8 and 3^2=9. So to undo 2+3=5 or 3+2=5 you would go 5−2=3 or 5−3=2. To undo 2*3=6 or 3*2=6 you would go 6/2=3 or 6/3=2. To undo 2^3=8 you would go 3root(8)=2 or log2(8)=3. To undo 3^2=9 you would go 2root(9)=3 or log3(9)=2.
thank you, sir! that is a great teaching and I'm also a teacher from Myanmar! And this come up to me as an another idea for my teaching method for this topic! Really grateful for this!
Thank you so much, sir. that was very easy and basic maths but you explain it very nicely with an analogy of time. I like the way you link simple things with some understanding.
I really wanna thank you truly from the depth of my heart. You are an amazing teacher. Tomorrow is my test and I hope I will get the best grades. Again tysm.
dammn i'd wake up early for this class. Whenever i ask my math teacher a question, he'd just say the equation and solution a couple of times as if i'd magically get it... lucky bunch of students

French people can't keep up with anything they don't already know -- or think they know ... But if you REALLY are "confused" with such a small thing (which I doubt), it is because French language is utterly POOR, compared to English (more than twice less words !).
Brilliant and well done as this effective explanation. As an idea covering 'log' can help when hinting at the connections to answer. The relationship might be obvious - so to speak.
This class seem so ungrateful to have such a good teacher, even I was answering his questions from behind my screen and I’m a GCSE student... don’t know what this class is but I’m presuming they’re A-Level seeming as they’re doing logarithms
I have some questions I would like to ask Why is the log 327 one more challenging What does it mean it is more challenging What is a whole number and why is it not a whole number What is a power And why is do we say what power do we have to raise this to What is root 3 How come the first to is equal to three What does equal mean What is the small numbers in front the numbers How come instead of doing it 4 times we do it six times What does it mean to confirm and what is the other way we can confirm What is index notation What is a square root sign Why did you wire 3 with 1/2 on top of it and said 3 to the power of a half

Excellent teacher. We did log to base 10 in our math, but now after 54 years, I am understanding what it truly meant.👍
🤣Funny, I just learned it today and I'm 55. Glad to see others my age and higher still working to understand maths. This guy ROCKS!!!!!
Great teaching @2:03 How you used the student's attempt to reach the answer through a lesson was awesome.
You can also say, how many time can you divide the result by the base until you get 1. So 3^4=81 and log3(81)=4 then
81/3=27
27/3=9
9/3=3
3/3=1
Four total steps so 4 is the answer.
As for the log.sqrt3(27) you can first square the base and then work with 3 and then empower it
So (sqrt3)^2=3 obviously and then divide 27 by 3 and then the answer by 3 and again so
27/3=9
9/3=3
3/3=1
So three times, 3^3, but 3 wasn’t the base.
Rewrite 3 as in the base form (sqrt3)^2 and power that by your amount of steps
(sqrt3^2)^3 that’ll be (sqrt3)^(2x3) or (sqrt3)^6 so answer is 6
Hope this will was clear enough and gave you another perspective on this :)
Would you say it's mentally more efficient to reason like this in order to obtain an answer?

In 12th grade now, saving these videos to show my son/daughter/child in the future.
points at sqrt(3): "That looks gross"

that surprised me initially because my math teacher says similar things: "that makes me uncomfortable", "that's ugly", and such.
The power function has two opposites; root and log, unlike add and multiply which both have one opposite each; minus and divide respectively.

OMG life changing!!🤩🤩🤩
I can't thank you enough for helping me Woo that was great!
I have some questions I would like to ask
Why is the log 327 one more challenging
What does it mean it is more challenging
What is a whole number and why is it not a whole number
What is a power
And why is do we say what power do we have to raise this to
What is root 3
How come the first to is equal to three
What does equal mean
What is the small numbers in front the numbers
How come instead of doing it 4 times we do it six times
What does it mean to confirm and what is the other way we can confirm
What is index notation
What is a square root sign
Why did you wire 3 with 1/2 on top of it and said 3 to the power of a half
If you were my teacher in school.. I would have been a scientist by now
Its never too late. Still you can be. :-)
thank you king i wish i had your class
Thank you sir very much.I wish if you could teach in our school.
Are u indian
mr guy is way too skilled at teaching
Never thought I'd understand logarithms
