The problem I first had when I started Algebra class were the Letters.
I got held back because I had trouble understanding the logic as to how you can do an equation with letters, and not numbers.

I even almost reach a point where I thought all of it was just nonsense and crap.

It then dawn on me later they were represent a possible number, not an actual number.

The only exception is "e" that represents a fixed irrational value.

not always, for example in Physics "e" can stand for the elementary charge (in fact both meanings are used, but we rely on context to distinguish between them. it's not difficult since the 2.71828... e is always written as the base of an exponentiation).

EDIT: on the other hand, I've never seen the letter "o" used for anything... I wonder why.

Because its just simple round shit.

lol, maybe...
or because it can be confused with 0...

I use it anyways when I'm calculating something, along with cyrillic letters. Greek ones are very boring.

Seriosly? I find Omega amazing!

don't misinterpret me, they are fine, but for naming parameters in science they are too overused XD

Good point, I never thought of that.

Well, "o" may not be used to represent unknowns or constants, but it's still used a lot in geometry to represent points.

that's true! Also I just remembered the big-o and small-o notation.
But still, I have yet to see a constant denoted by "o"

big O and small o

maybe?
