Work Step by Step

Use the order of operations to simplify the expression: $$8-3[-2(5-7)-5(4-2)]$$ Working from the innermost grouped operations: $$=8-3[-2(-2)-5(2)]$$ Then within the grouped operations, multiplication and division are done in order left to right: $$=8-3[4-10]$$ Complete the grouped operations: $$=8-3[-6]$$ $$=8+18$$ $$=26$$
