Help a lot of students! I am actually in 5th grade right now and some of your videos really helps me to prepare for the future! Thank you!

[andreakuska]

Thank you so much for this. I have been really, really struggling with slope despite a ton of books and using khan academy. I kept thinking I had it down and then got it wrong no matter what! This video explained it so clearly I had no problems figuring it out. What a relief.

[RobertChen-jwsb]

I'm so glad you are a thing bro, i started watching your videos in 4th grade trying to get into a gifted class and i've got in thanks to you!👏👏👏👏

[jdras]

Great video as always!! but...….. 4 x 21 is 84, You said 84 but wrote 81@ 6:44. :) Thanks!!

[whiteroomentertainmenttv]

I've been struggling in 10th grade math, this helps a lot thanks!

[Kkuii]

I’m in my first year in college and I watch your tutr ty sm

[MYPETDAILYVLOGS]

Now I am in 6th and I just want to learn more then my math topics then I got your video and it was very nice and I able to understand it was good thank you for this video

[Shivam-mbbt]

Best freaking teacher man love from Pakistan ❤

[HAJIMUHAMMADMOUSSAEshaqZada]

Simple yet so powerful &helpful.
Really like ur methods...
there's no edit in the background unlike others(likeable)❤.

[notcharlie]

in the first minute 30, you made me understand this much more

[leahbowers]

For your last example, the one with fractions, you said that 4 x 21 is 84, but you wrote 81.

[MrCheeseJr.]

studying for my algebra 1 exam and I really needed this

[farmertice]

The answer to the last one, I believe, should be -75/91 because you wrote 81 instead of 84.

[rodylopez]

I'm in 6th grade and I have learned a lot from your videos because I want to get prepared for 7th and 8th grade when they teach me algebra.

My brain just melted😔 5:03 Slope of (2/3, 4) & (5, 3/7)
2/3=x1, 4=y1 5=x2, 3/7=y2
slope formula=y1-y2/x1-x2
4-3/7/2/3-5
3/7=0, 428 2/3=0, 666
0, 428=0, 43 0, 666=1
4-0, 43/1-5
4-0, 43 4-0, 03=3, 97-0, 4=3, 57-0=3, 57
1-5=-4
3, 57/-4=3, 57/4≠3, 57/-4=3, 57/4
0, 07/4=0, 01 rest 0, 03/4=0, 030/4=0, 007 0, 01+0, 007=0, 017
0, 5/4=0, 1 rest 0, 1/4=0, 10/4=0, 02 rest 0, 2=0, 12
3/4=3, 0/4=0, 7 rest 2/4=2, 0/4=0, 05=0, 75
Slope=0, 017+0, 02+0, 75=0, 787

8:11 ain't it supposed to be 84? 4*21?

[andLive]

This helped me, I have a B in math, now I understand pretty well.

[faenigma-hh]

while at the last example 6:38 while multiplying 21 by 4 isnt it 84, u wrote 81 so i think it changed the whole equation, i dont understand that part

[DeMarcusAndres]

thank you i have a test today and i will pass thanks to you

[leoguy]

defenitly better expliation then my teacher
