Question 772539: (8-10)[4-|7(-2)|] the directions say "simplify each expression using the order of operations (PEMDAS)." I do not know what the bars and other things are (I know the parenthesis though)! By the way the line by the 7 is a bar NOT a 1!

(8 - 10)[4 - |7(-2)|]
= (-2)[4 - |-14|]
= (-2)[4 - 14]
= (-2)(-10)
= 20
