Exercise 9 Page 187

First, evaluate the expression inside the parentheses.

10

Practice makes perfect

According to the order of operations, expressions inside parentheses are evaluated first, followed by exponents, then multiplication and division, and finally addition and subtraction are evaluated last. We can use the acronym PEMDAS to help us remember the correct order!

Let's follow the order of operations and simplify the given expression. Remember that we multiply and divide from left to right. Here, we will perform the division before the multiplication.

Operation	Before Simplification	After Simplification
Divide	24÷ 4 * 2 - 2	6* 2 - 2
Multiply	6* 2 - 2	12 - 2
Subtract terms	12 - 2	10

The expression is equal to 10.
