To answer you guys, I wasn't sure why I thought that would work. Right now I'm just scheming everything I think could possibly work, in an attempt to get the right answer. Often its wrong, but at least they give you the right answer if you want them to.
Now I'd like to ask about a use case for abs(). Absolute value from zero. Why would we ever need to know that? It always just returns the same number. Maybe it doesn't have a - sign in front of the number anymore, but I think we can figure that out on our own. So you'd say abs(125) and it of course returns 125. Same for -125. You get 125.
I'm sure there is something lying in wait in the future, when it comes to a use for this function. But I'd like to know what it is, and how abs() is helpful.
