Question:

Which of the following is equivalent to (-8+(17-9)*4+7)?

A
31

Explaination

The order of operations requires evaluation of the expression inside the parentheses as a first step. Thus, the expression can be re-written as -8+8*4+7. Now, the order of operations next requires all multiplications and divisions to be computed as they appear from left to right. Thus, the expression can be written as -8+32+7. Finally, the addition may be computed as it appears from left to right. The expression simplifies to 24+7, or 31.
