Y'know, Something I always needed from math teachers was to explain WHY. The what only gets you so far, The how lets you know what got you where, But the WHY Is literally so important and I feel some teachers really over-look it. But here, I understand things very well because its explained fully in a good way

One of the reasons that Brian is such an excellent teacher, is that he doesn't do all the steps to one problem. He repeats the steps on multiple problems as he goes (for repetition) students learn much better this way in my experience! Kudos Brian!

For anyone that got confused when he was subtracting numbers around 5:55. He is just subtracting the equivalent amount he just added to the inside of the parenthesis. ex. -3(x^2-2x)-1 >> -3(x^2-2x+1) -1 (+3) or -3(x^2-2x+1) -1 -1(-3)

Apparently you and my teacher are beefing because anytime he teaches i understand but sometimes i don’t understand a thing. My teacher kind of likes me and dislikes me mostly bc im the “disturbance” of the class and also im one of the smartest and he put in the back seat, i can’t see and i can’t learn well from all the way back. So anytime he teaches he knows i don’t get it and he tells me “You’ll be alright” then I just go home to watch your videos next day I come back and he’ll think he’ll catch me “lacking” but I just answer his questions with ease thanks to you!!!! My grade in his class is a 95% and thanks to you, your simple teaching and a lot of praying and hard work. I wish there was a way to repay you because only God knows what i’d have in his class if not for you sir.❤️❤️❤️
