Yeah, we ALL KNOW THAT IT WORKS with no matter what two numbers you add together. BUT WHY???
That's what I want to know.

Is this algebra, a mathematical equation!!!

Even my son can't figure out WHY??

See, I know THAT it works, I would love to know how the heck it always comes up with the same symbol. ALL THE TIME.

We need some math geniuses here!!!!!
