Chapter 7-7 "Order of Operations"

Front

What is the order of operations in mathematics?

Back

The order of operations is a set of rules that determines the sequence in which calculations are performed. The order is: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What does it mean to solve an expression in parentheses first?

Back

It means to perform the operations inside the parentheses before any other operations in the expression.

What is the result of 18 − 4 × 2?

Back

10 (Remember to multiply before subtracting!)

Front

What is the first step in the order of operations?

Back

The first step is to solve any expressions inside parentheses.

Front

What do you do if there are multiple operations in an expression?

Back

Follow the order of operations: solve parentheses first, then exponents, followed by multiplication and division from left to right, and finally addition and subtraction from left to right.

What is the result of 4 + 3 × 2?

Back

10 (Multiply first: 3 × 2 = 6, then add: 4 + 6 = 10.)
