YOU ARE ABSOLUTELY AMAZING! I've searched so many videos trying to understand how to do this and in two 8-minute videos, you explained it so clearly and simply. Thank you so much!

Thank you so much, a 3 hour lecture left me nothing but confused and you just explained it in under 20 minutes!

You're the absolute best man. When I was going through undergrad math in college, my institution implemented your videos into every homework assignment we had all the way from algebra to calc 3 and beyond. Thank you for what you do.

Unambiguous and straight to point. Maths is fun and adventurous only with the right teacher.
Thank you

Awesome video! Was struggling with my revision until I chanced upon this. Thank you so much!

Thank you. Much clearer than my prof. I still have questions... (just the differences of steps and rules my prof uses...) but this provided a good understanding of the concept

2021 and it's still gold.
I wish my Linear Algebra teacher would be like you

My english is horrible, but its way better watching this than any portuguese video

Having online classes right now due to Covid-19 and this video is a goddamn life saver

[mrnobody]

The best tutors are definitely from youtube. TQVM

thanks for the video, our unsung hero. Wonder why its always complicated when a professor teaches the subject, and its always understandable when someone on youtube does it

[mounirelkatmour]
