Dare i felt a lil conscious about the fact of mentioning something like this for it stands out to be silly to the idea being strictly explained but i laughted the hecks out on this tooooo 😂😂😂😂😂😂
Hahaha I can't read titles. I watched about three minutes of this thinking it was about muscial intervals before going 'wait-'. Ah well, learned something new.
Thank you so much on helping me understand this, my teacher talks way to fast for me to keep up and understand at the same time, you explain it more detail and I thank you for that.
Omg this was great. The fact that you use so many example and repeat them makes me understand so much better! My school maths teacher is like a 2 compared to you lol. Thanks!
After this video ended, I just shouted "Thank you so much". But sad, you aren’t going to hear this. I'm from Bangladesh.. So I was doing my homework.. My teacher finished this chapter year ago.. But I haven’t. Now I don’t want to knock for him for this petty question (not petty for me, definitely not). THANK YOU SO MUCHHHH.
Is [4,4] and interval? My basic understanding of an interval is that it's just stuff between two points or values. So I don't get how something like [1,2]intersection[2,3] is an interval? Isn't that just the set {2}?

you don't know what is the number but when it is determined like x less than or equal 2 so 2 needs bracket then it is going to be paranthesis negative infinity ;2 bracket
What do you do when you have a number that is the same as the end point for your interval? like, 40 - 50 but there is a 50, and your next interval is 50 - 60? Do you include them both? or just the one on the left or right?
No. Cartesian coordinates are represented by (x, y) Plot them on graph and they're obviously different. -3 comes first on the no. line before 2 so the correct way of writing is [-3,2]. Use the number line to understand.
it is 10:40 pm at night and im still working on homework, i havent even gotten to do any of my missing assignments and all of them are do tomorow. Guess whos defininetly getting kicked out of honors for the big fat D im getting in my Algebra class!!!!
This guy has saved me SO MANY TIMES for 5 years now, THANK YOU!!!!!!!!!! (Best math videos EVER!!)
"NINENINENINENINENINENINE" I burst out laughing when he said that
Dare NEIN NEIN NEIN NEIN NEIN NEIN
Dare i felt a lil conscious about the fact of mentioning something like this for it stands out to be silly to the idea being strictly explained but i laughted the hecks out on this tooooo 😂😂😂😂😂😂
Where is that?
Don't lie for likes
Studies s no for real kid where is it?
This math video is great. Everything is well described and repeated and I like that. Thanks!
oh my gosh can you please replace my Algebra 2 teacher lol?
Fr
Can you replace my Pre-Calc teacher?
facts
yes please
I second this!
Actually for me, i think you understand this easily because it's now familiar to you when ur teacher taught you...
bruh
Hahaha I can't read titles. I watched about three minutes of this thinking it was about muscial intervals before going 'wait-'. Ah well, learned something new.
Me too 😭😭
thank you so much I didn't understand my teacher when he explained it
me teacher didnt even explain it to the class
and this is why i LOVE khan academy
Yo, legit this guy can teach better than any other teacher. And I am literally talking about k-12, continuing to university.
God bless you man you are my saviour
So my teacher took 2 hours to explain this from which I didn't understand half of it and this guy explained it in 9 minutes??
Thank you so much on helping me understand this, my teacher talks way to fast for me to keep up and understand at the same time, you explain it more detail and I thank you for that.
Sal, my lord and saviour, I now understand
I still don't i don't even know anything we done in class this whole month im doomed
I am exactly the 4000 like!!!
MOST HELPFUL THING GOD MADE ON EARTH
Oh you are my lifesaver when it comes to maths🙏
My university lecturer spent an hour explaining intervals and you explained it in 10 minutes
ur the best!!!!!!
Good explainantion
Omg this was great. The fact that you use so many example and repeat them makes me understand so much better! My school maths teacher is like a 2 compared to you lol. Thanks!
most straightforward and specific explanation on intervals, thanks!
Thank you so much. You don't know how much this helps us students. God bless you so much!
This is clearer than what my 10th grade math teacher taught us.
Quarantine got me a better teacher
Thank you so much! I was so confused before
That's some beautiful stuff.
THANK YOU!! Clear and easy to follow. Thank you for also showing the multiple ways to express the intervals.
If you change the speed to 0.5 from 4:14 - 4:23, you will notice that Sal drank one too many before the making of this video
Lmao 😂 underrated
0.25 is even better
Thank you!
Wish I had profs like this!
Excellent and easy to understand - as always...thank you Khan Academy!!!!!!
thanks alot sir awesome video
all doubt cleared
awesome this helped me so much!!!!!!
Best video I have found for this. Finally clicked, thank you XD I need all the special help lmao.
The concept was explained in the best way possible.
Loved it and thank you.
Your the only way I'm getting through IB math :3
Helped a lot thank you
Thanks for the help, my teacher never taught us this but it was on the review.
ive never related so much
Utter incompetence
this helped me so much! God bless your soul!
Thanks Sal. You saved me.
nice video , it's help alot
You are a legendary teacher
I like this video. Had a hard time understanding this but now its clear. Hopefully I pass my test now.
Helped clarified ALL of my problems that I had!
Sal used some set theory notation, nice!
2:16 Congratulations Khan, you created a new word "mathy"
Excellent explanation... set notion math is literally like doing computer programming on paper for humans to compute.
After this video ended, I just shouted "Thank you so much".
But sad, you aren’t going to hear this. I'm from Bangladesh..
So I was doing my homework.. My teacher finished this chapter year ago.. But I haven’t. Now I don’t want to knock for him for this petty question (not petty for me, definitely not).
THANK YOU SO MUCHHHH.
thank you so much!
Woah is it only me or did his voice change??
Kind of sounds like Jeff Bridges, but less country boy in his voice.
Buttered pAWPcorn So an Indian Jeff Bridges eh
@Charlie Robertson *Bangladeshi American
Perfectly clear. Thank you!
What is the software you use for this videos? Thanks!
Perfect explain,Thanks
Thank youuuu♥️♥️♥️♥️
Thank you 💜🎂
God bless you and you have a good day 💕
I love you teacher

Thanks man!
Thanks It helped alot for me to do myy h/w
aw, thanks so much! may i just ask what program are you using?
Gabriel Fabián I honestly think he's using ms paint, I might be wrong
He uses bamboo brush and pen.
thank you sssooo much
Thankss !!
Thank you 💕🙏😌🙏💗
Why do we use closed bracket at infinity??
you don't know what is the number but when it is determined like x less than or equal 2 so 2 needs bracket then it is going to be paranthesis negative infinity ;2 bracket
What do you do when you have a number that is the same as the end point for your interval?
like, 40 - 50 but there is a 50, and your next interval is 50 - 60? Do you include them both? or just the one on the left or right?
If 50 is included then you include them both 40-60
Excellent tutorial...thanks!
You are my best and now online teacher I want to look up if I'm up to learn something or get motivated by the hashtag #youcanlearnanythings
Is [-3, 2] equal to [2, -3]? Are they mathematically similar in properties of Cartesian coordinates?
I am a math noob and would love some help.
definitely not they are not the same.
@@sagar-uj1nb Why? These are not coordinates. But show the scale between the 2 numbers.
No.
Cartesian coordinates are represented by (x, y)
Plot them on graph and they're obviously different.
-3 comes first on the no. line before 2 so the correct way of writing is [-3,2].
Use the number line to understand.
I was looking for music theory😂
listen on 2X at 4:08
Thank u sir
he has an optical mouse
how will I write the interval notation of a number line with no graph at all?
With a pen
Does this apply the same way to parabolas?
thank you
it is 10:40 pm at night and im still working on homework, i havent even gotten to do any of my missing assignments and all of them are do tomorow. Guess whos defininetly getting kicked out of honors for the big fat D im getting in my Algebra class!!!!
what about set notation can u make a video about that?
tysm
We can lose the 'x is a member of all real numbers' and just have -4
Thanks
So in this kind of problems, we can only express interval notations??
what’s the name of orange and green interval please ? great video
kindly specify the notation for half closed and half open interval in this video.
What is your writing software?
This helped me so much. Thanks so much!
explained more in nine minutes than my college professor did
Nice!!!!!!!
does the Greek E represent belongs to? that is what i learned
Who’s in 7th Gradeee.... help me
8th grade 😕
@@sukeynarules7754 same cry
Wow this is so clear i was watching another video abt algebra and them be like now we apply - infinity and infinity me👀😳🤔🤔😕😔
so what will i use if a solution set is 0
2:41 sir u said that sign is not epsilon in your previous video. And now you are saying it is.
what if there's more than one digit that is excluded from the interval?
Me: *still doesn't understand*
