      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?

        It’s like taking a signed int and turning it into an unsigned int though. It doesn’t become positive it just loses its sign.

      If your task is to turn any number that could be negative into positive then you would use abs right?
