    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

He's also rude to students who he finds annoying, he stands in front of the board so we can't see, and he doesn't explain things. He just does math problems and expects us to understand what he's doing.

    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.❤️❤️❤️

    I don't comment often, but I had to say this. I've had trouble with this all day. Found this video and hoped for the best.
    I am now subscribed. I'm recommending this channel to a friend. Thank you very much.
    Live Long and Prosper

    I've watched so many videos on this, and I can't believe it! I actually understand this after so many videos and lessons on it, and only in 8 minutes. Amazing. Thank you so much.

    You broke down in 8 minutes what I spent several hours "reviewing", well done Sir. Also, you had several good examples of different cases. Doing them simultaneously helped reinforce the concepts and steps. I'd give 2 thumbs up but I have a beer in my left hand...

    An intuitive approach! The steps were explained clearly, showing precisely where each step comes from. Thank you!
