Me i don’t understand how to do this

Absolute value is how far a number is from 0. Fifteen would be 15 spaces away from zero and -3 would be 3 spaces away from zero. The opposite of a number is the number on the other side of zero, as far away from zero as that number. For example, the opposite of 7 is -7.
