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).

Front

What does PEMDAS stand for?

Back

Parentheses, Exponents, Multiplication and Division, Addition and Subtraction.

Front

Calculate: 5 + 2 x 3

Back

11 (First, multiply 2 x 3 = 6, then add 5 + 6 = 11).

Front

Calculate: (8 - 3) x 2

Back

10 (First, subtract 8 - 3 = 5, then multiply 5 x 2 = 10).

Front

What is 2^3?

Back

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

Front

Calculate: 10 - 4 + 2

Back

8 (First, subtract 10 - 4 = 6, then add 6 + 2 = 8).

Front

Calculate: 12 ÷ 4 x 3

Back

9 (First, divide 12 ÷ 4 = 3, then multiply 3 x 3 = 9).

Front

What is the result of 7 + 3 x 2 - 1?

Back

12 (First, multiply 3 x 2 = 6, then add 7 + 6 = 13, and finally subtract 1 = 12).

Front

Calculate: 15 - 3 x (2 + 1)

Back

6 (First, solve inside the parentheses: 2 + 1 = 3, then multiply: 3 x 3 = 9, and finally subtract: 15 - 9 = 6).

Front

What is the value of 9 - 3^2?

Back

6 (First, calculate 3^2 = 9, then subtract: 9 - 9 = 0).
