absolute value

Answer 2

Those probably represent absolute value. Absolute value of a number means: if the number is greater than 0, leave it alone, if it is less than zero, take its negative.

Answer 3

It's absolute value, so it's the number's distance from zero on a standard number line. So -20 would be 20 units away from zero
