STEP 1

Assumptions1. We are given the expression 4+[(8+9)]4+[-(8+9)] . We need to simplify this expression using the order of operations, which is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). This is often abbreviated as PEMAS.

STEP 2

First, we need to simplify the expression inside the parentheses. According to the order of operations, we perform operations inside parentheses first.
4+[2(8+9)]4+[2-(8+9)]

STEP 3

Now, add the numbers inside the parentheses.
+[2(17)]+[2-(17)]

STEP 4

Next, perform the subtraction inside the brackets.
4+[15]4+[-15]

STEP 5

Finally, perform the addition operation.
4154-15

STEP 6

Calculate the final result.
11-11The correct choice is A. 4+[2(8+9)]=114+[2-(8+9)]=-11
