CPM Homework Help : CC3 Problem 8-91

Recall that vertical lines around a number are the symbol for the absolute value of a number. Simplify each expression.

Hint:

There cannot be a negative absolute value.

More Help:

When a negative is outside of the absolute value symbol, it stays a negative.
