Order of Operations

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, 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 and Division (from left to right), Addition and Subtraction (from left to right).

Front

Solve: 3 + 4 x 6 - 4 = ?

Back

First step is multiplication: 4 x 6 = 24, then 3 + 24 - 4 = 23.

Front

What is the first step in solving 5 - 6² ÷ 4 - 3?

Back

The first step is to calculate the exponent: 6² = 36.

Front

Solve: 5 - 36 ÷ 4 - 3 = ?

Back

First, divide: 36 ÷ 4 = 9, then 5 - 9 - 3 = -7.

Front

True or False: 2 + (4 x 5 - 2) + 8 = 28

Back

True.

Front

What is the value of (7 + 41) ÷ 2 – 15?

Back

First, add: 7 + 41 = 48, then divide: 48 ÷ 2 = 24, finally subtract: 24 - 15 = 9.

Front

What is the role of parentheses in order of operations?

Back

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

Front

What is an exponent?

Back

An exponent is a number that shows how many times to multiply a number by itself.

Front

Solve: (2 + 7 - 1) ÷ 2² = ?

Back

First, calculate inside the parentheses: 2 + 7 - 1 = 8, then 2² = 4, finally 8 ÷ 4 = 2.
