What is a math concept or theorem that you wish there were a better explanation of?
It could be from arithmetic: Why is adding fractions so complicated?
From grade-school algebra: Why does the teacher get so sad and angry if I just √(x²+y²)=x+y
From the calculus: Why do I need to write dx with the integral?
or beyond.
@futurebird Sums. As in the functions that begin with a capital Sigma. But it's been so long (class of '97) I don't even remember what part I don't understand.

Do you program with "for" loops ever? If not no biggie, but if you do? That's what those are. They are "for loops" in math notation.

It occurs to me you may have been vexed by the analysis of infinite sums, which is another matter.

@futurebird Like I said, it's been a minute.
I think that may be it, because it's part of why I found integral calculus so hard in university. I understood an integral of a function being the area under it's graph, so it's the sum of all the Y values along the X axis, and I could follow the professor working out the answer, but I couldn't figure out how to make it happen by myself.Mind you, I dropped out and tried a few other things until I discovered that I really like factory work, so grade 10 math more than got me by professionally.
