Of course I don't know mathmatics, can't even spell it correctly, so instead will share videos of those who do understand math.
Here's the thing, in school I was way to hyped up to even want to concentrate on math, no way, to many distractions, girls, your friends, joking around.
Years later though, did take a bit of math in college and found that as a much more mature individual and because was paying for courses, that I did a lot better, sadly couldn't finish the full year out.
But what that told me is the reason most fail at math when young, is not cause they're, we're dumb, it's just we're not able to concentrate in younger years, unless like a geek type.
But at the high school I went to, even some of the Jock guys were good at math, they were like geek/Jock hybrids.
Anyways, Math is boring, especially if learning it all over again just to prove you can and to teach self how to concentrate and focus on solving problems again.
