Order of Operations (no exponents)

Front

What is the Order of Operations?

Back

A set of rules that determines the correct sequence to evaluate a mathematical expression. The order is Parentheses, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Front

What do you do first in the expression: 45 - 2 x (15 - 3)?

Back

You solve the expression inside the parentheses first: (15 - 3) = 12.

Front

Evaluate: 10 + 45 ÷ 9 − (14 ÷ 2)

Back

First, divide 45 by 9 to get 5, then divide 14 by 2 to get 7. The expression becomes: 10 + 5 - 7 = 8.

Front

What is the result of 7 ÷ 1 − 6?

Back

First, divide 7 by 1 to get 7, then subtract 6. The result is 1.

Front

In the expression (12 + 10) ÷ 10 · 14 − 6, what should you do first?

Back

You should solve the expression inside the parentheses first: (12 + 10) = 22.

Front

What step would you do second in the expression (4-2) x 9 + 7?

Back

The second step is multiplication: (4-2) = 2, then 2 x 9 = 18.

Front

What does 'Parentheses' mean in the Order of Operations?

Back

Parentheses are used to group numbers and operations that should be calculated first.

Front

What is the result of the expression 8 + (3 x 2)?

Back

First, calculate inside the parentheses: 3 x 2 = 6. Then, 8 + 6 = 14.

Front

What is the difference between Addition and Subtraction?

Back

Addition combines numbers to get a larger number, while subtraction takes one number away from another.

Front

What is the result of 5 x (2 + 3)?

Back

First, calculate inside the parentheses: 2 + 3 = 5. Then, 5 x 5 = 25.
