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

Simplify: 3 + 5 x 2

Back

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

Front

Simplify: (4 + 6) ÷ 2

Back

5 (First, add 4 + 6 = 10, then divide by 2).

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: 12 - 4 x 2

Back

4 (First, multiply 4 x 2 = 8, then subtract from 12).

Front

What is the result of 8 ÷ 2(2 + 2)?

Back

16 (First, solve the parentheses: 2 + 2 = 4, then 8 ÷ 2 = 4, and finally 4 x 4 = 16).

Front

Simplify: -2 x (3 + 8 ÷ 4)^2

Back

-50 (First, solve the parentheses: 8 ÷ 4 = 2, then 3 + 2 = 5, and finally -2 x 5^2 = -50).

Front

What is the first step in solving an expression with parentheses?

Back

Evaluate the expression inside the parentheses.

Front

Solve: (7 + 41) ÷ 2 – 15

Back

9 (First, add 7 + 41 = 48, then divide by 2 = 24, and finally subtract 15).
