Question

Felica is trying to simplify the expression 9 + (8 x 9) - (18\3

Answer 1

The answer is 75.

Explanation:

First, we apply the rule of PEMDAS (or whatever order of operations rule you have learned). In this equation, we first solve inside the parentheses.

8 x 9 = 72

18/3 = 6

Now, our equation has become 9 + 72 - 6. We can solve this left to right:

9 + 72 = 81

81 - 6 = 75
