TLC Order of Operations Flashcard

Front

What is the order of operations in math?

Back

The order of operations is a set of rules that tells you the sequence in which to solve different parts of a math problem. It is often remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What does 'multiplication' mean?

Back

Multiplication is a mathematical operation where a number is added to itself a certain number of times. For example, 4 x 3 means 4 added together 3 times (4 + 4 + 4 = 12).

What is the first step to simplify the expression 3 + 4 x 6 - 4?

Back

The first step is multiplication. You should calculate 4 x 6 first.

Front

What is the result of 5 x (6 - 3)?

Back

The result is 15. First, solve the parentheses: 6 - 3 = 3, then multiply: 5 x 3 = 15.

Front

What does 'division' mean?

Back

Division is a mathematical operation where a number is split into equal parts. For example, 12 ÷ 4 means splitting 12 into 4 equal parts, which equals 3.

Front

What is the result of (24 - 16) ÷ 8?

Back

The result is 1. First, solve the parentheses: 24 - 16 = 8, then divide: 8 ÷ 8 = 1.

Front

What is the result of 18 + (6 - 2) x 2?

Back

The result is 26. First, solve the parentheses: 6 - 2 = 4, then multiply: 4 x 2 = 8, and finally add: 18 + 8 = 26.

Front

What does 'addition' mean?

Back

Addition is a mathematical operation where two or more numbers are combined to make a larger number. For example, 3 + 2 = 5.

Front

What is the result of 2 x 9 ÷ 3?

Back

The result is 6. First, multiply: 2 x 9 = 18, then divide: 18 ÷ 3 = 6.

Front

What is the purpose of parentheses in math?

Back

Parentheses are used to indicate which operations should be performed first in a math expression.
