This man needs to make his own youtube channel with his own production team and i bet people would watch it religiously; people with his kind of enthusiasm for math are the kind of people that make others want to listen and learn.

I am a grandma (college professor of literature) trying to support her grandson's 9th-grade math lessons. Your videos are clear, focused, and encouraging. You have a humble and humorous approach that makes math fun and doable!

Ok Ed I’m not following why that 4 was changed to a negative? Seems like the sign would change but the 4 would’ve stayed positive…
