Lesson Practice - Order of Operations

Front

What is the Order of Operations?

Back

The Order of Operations is a set of rules that determines the sequence in which calculations are performed in a mathematical expression. The acronym PEMDAS helps remember the order: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What does PEMDAS stand for?

Back

PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Front

Simplify: 3 + 5 x 2

Back

13 (First, multiply 5 x 2 = 10, then add 3.)

Front

Simplify: (8 - 3) x 4

Back

20 (First, subtract 8 - 3 = 5, then multiply 5 x 4.)

Front

What is the first step in the Order of Operations?

Back

The first step is to solve expressions inside Parentheses.

Front

What is the result of 10 - (2 + 3)?

Back

5 (First, solve inside the parentheses: 2 + 3 = 5, then subtract: 10 - 5 = 5.)

Front

Simplify: 6 ÷ 2 + 3

Back

6 (First, divide 6 ÷ 2 = 3, then add 3: 3 + 3 = 6.)

Front

What is the value of 2 x (3 + 4)?

Back

14 (First, solve inside the parentheses: 3 + 4 = 7, then multiply: 2 x 7 = 14.)

Front

Which operation do you perform first in the expression 5 + 2 x 3?

Back

Multiplication (You perform multiplication before addition, so 2 x 3 = 6, then add 5.)

Front

Simplify: 4 + 6 ÷ 2 x 3

Back

22 (First, divide 6 ÷ 2 = 3, then multiply: 3 x 3 = 9, then add: 4 + 9 = 13.)
