I might be wrong, but I thought absolute values weren't positive or negative?
I don't understand this argument. I've heard high school teachers decree it as a mathematical truth before.
Do we all agree absolute value is a function from reals to reals? If so, the absolute value of any real number is nonnegative. It can be zero or any positive numbers.
Case closed, right?
If your task is to turn any number that could be negative into positive then you would use abs right?
