–|–4+1| + (–4) |–7+–8| What is the value of the expression?
the "|" signs represent absolute value
absolute value of -3 is 3 (notice the sign goes away)
absolute value of 3 is 3
when you take absolute value of a number you are finding the number's magnitude
|-4 + 1| = |-3| = 3
|-7 + -8| = |-15| = 15
-1 * 3 + -4 * 15
-3 - 60
-63
