are all equal to 7. In each case, you find the absolute value of the number, or expression
inside the absolute value bars. The absolute value of a positive or a negative number is always positive, so all
these absolute value expressions equal 7.
both equal
In each case, you find the absolute value of the number inside the absolute
value bars. This absolute value is positive. Then you find the opposite of the absolute value, so the result is
negative.
