To solve this problem -3(8/9) ÷ 66.9[9 (-8.9 + 9/5) .01] we must start with
1. Solve this bracket [9 (-8.9 + 9/5) .01] at first
2. Multiply the answer of the bracket by 66.9
3. Multiply -3(8/9) and divide the answer by the product of the previous
step
In [9 (-8.9 + 9/5) .01]
∵ (-8.9 + 9/5) = (-8.9 + 1.8) = -7.1
∴ [9 (-8.9 + 9/5) .01] = [9 (-7.1).01]
