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.

Front

What does PEMDAS stand for?

Back

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

Front

Solve: 4 + 3 x 2

Back

10 (First, multiply 3 x 2 = 6, then add 4).

Front

Solve: (5 + 3) x 2

Back

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

Front

Which operation do you perform first in the expression: 6 + 2 x 3?

Back

Multiplication (2 x 3 = 6, then add 6).

Front

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

Back

0 (First, calculate 2 + 3 = 5, then multiply by 2 = 10, and finally subtract from 10).

Front

Solve: 12 ÷ 4 + 5 x 2

Back

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

Front

What is the first step in solving: (8 - 3) + 2 x 5?

Back

Parentheses (First, calculate 8 - 3 = 5).

Front

Solve: 3 + 6 ÷ 2 - 1

Back

5 (First, divide 6 ÷ 2 = 3, then add 3 + 3 = 6, and finally subtract 1).

Front

Which operation is performed last in: 7 + 2 x (3 - 1)?

Back

Addition (First, calculate inside the parentheses, then multiplication, and finally addition).
