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

Front

Solve: 8 + 2 x 5

Back

18 (First, multiply 2 x 5 = 10, then add 8).

Front

Solve: (3 + 5) x 2

Back

16 (First, add 3 + 5 = 8, then multiply by 2).

Front

What is the first step in solving: 4 + 3 x 2 - 1?

Back

Multiplication (3 x 2 = 6, then proceed with addition and subtraction).

Front

Solve: 5 x (2 + 3) - 4

Back

21 (First, add 2 + 3 = 5, then multiply by 5, and finally subtract 4).

Front

What is the value of 2^3?

Back

8 (2 raised to the power of 3 is 2 x 2 x 2).

Front

Solve: 10 - 2 x (3 + 1)

Back

6 (First, solve inside the parentheses: 3 + 1 = 4, then multiply: 2 x 4 = 8, and finally subtract: 10 - 8 = 2).

Front

What is the result of 6 + 4 x 2 - 3?

Back

11 (First, multiply: 4 x 2 = 8, then add and subtract: 6 + 8 - 3 = 11).

Front

Solve: 9 - (2 + 3) x 2

Back

-1 (First, solve inside the parentheses: 2 + 3 = 5, then multiply: 5 x 2 = 10, and finally subtract: 9 - 10 = -1).
