5.OA.1 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 common acronym to remember this order is PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Front

When there are no parentheses in an expression, how do you handle multiplication and division?

Back

You perform multiplication and division from left to right, depending on which operation comes first.

Front

What is the first step to evaluate the expression 5 x 9 + (8 – 2)?

Back

The first step is to evaluate the expression inside the parentheses: 8 – 2.

Front

What does the term 'evaluate' mean in mathematics?

Back

To evaluate means to solve or find the value of an expression.

Front

What is the result of the expression 4 + 5 x 2 – 3?

Back

The result is 11.

Front

How do you solve the expression (16 – 12) ÷ 4 + 9?

Back

First, evaluate the parentheses: 16 – 12 = 4. Then, divide: 4 ÷ 4 = 1. Finally, add: 1 + 9 = 10.

Front

What is the role of parentheses in the order of operations?

Back

Parentheses indicate which operations should be performed first in an expression.

Front

What is the difference between multiplication and addition in terms of order of operations?

Back

Multiplication is performed before addition in the order of operations.

Front

If an expression contains both addition and subtraction, how should it be evaluated?

Back

Addition and subtraction are performed from left to right, depending on which comes first.

Front

What is the result of the expression 3 + 4 x 2?

Back

The result is 11, because you perform the multiplication first: 4 x 2 = 8, then add 3.
