Order of Operations

Front

What is the Order of Operations?

Back

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

What does PEMDAS stand for?

Back

PEMDAS is an acronym for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction, which helps remember the order of operations.

Front

Simplify: 3 + 5 x 2

Back

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

Front

True or False: 6 + 2 x 3 = 24

Back

False (6 + 2 x 3 = 12, because multiplication comes before addition.)

Front

What is the first step in simplifying the expression: (8 - 3) + 4 x 2?

Back

The first step is to solve the parentheses: (8 - 3) = 5.

Front

Simplify: 10 - (2 + 3) x 2

Back

0 (First, solve the parentheses: 2 + 3 = 5, then 10 - 5 x 2 = 0.)

Front

What is the result of 4 x (3 + 5) - 6?

Back

26 (First, solve the parentheses: 3 + 5 = 8, then 4 x 8 - 6 = 26.)

Front

True or False: 5 + 3 x 2 - 1 = 10

Back

True (5 + 3 x 2 - 1 = 10, because 3 x 2 = 6, then 5 + 6 - 1 = 10.)

Front

What is the second step in simplifying the expression: 7 + 2 x (3 - 1)?

Back

The second step is multiplication: 2 x (3 - 1) = 4.

Front

Simplify: 12 ÷ 4 + 5 x 2

Back

14 (First, divide: 12 ÷ 4 = 3, then multiply: 5 x 2 = 10, finally add: 3 + 10 = 13.)
