There's no need, it's unambigious and the answer is 67.

But all these stupid questions are order of operations questions. Therefore parentheses are important.

if you want the answer to be anything other than 67 then you indeed need parenthesis, but there's no ambiguity in the original expression.

orange = 45/3 = 15
banana = (23- 15)/2 = 8/2 = 4
apple = (10-4) / 2 = 6/2 = 3
3+4+4*15 = 67

not using order of operation. basically reading 3+4+4*15 as (3+4+4)*15

Wrong. If you use common core, the orange is 20 because you have to round up to the nearest 10s.

The answer is actually 11 x 20, or 220.
