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: 3 + 5 × 2

Back

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

Front

Solve: (6 + 2) × 3

Back

24 (First, add 6 + 2 = 8, then multiply by 3.)

Front

True or False: Multiplication comes before addition in the Order of Operations.

Back

True

Front

What is the first step in the Order of Operations?

Back

Perform calculations inside parentheses.

Front

Solve: 10 - 2 × (3 + 1)

Back

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

Front

What is an exponent?

Back

A number that indicates how many times to multiply the base by itself.

Front

Solve: 4 + 3^2 - 5

Back

12 (First, calculate the exponent: 3^2 = 9, then add and subtract: 4 + 9 - 5 = 8.)

Front

True or False: Division and multiplication are performed from left to right.

Back

True
