What is the Order of Operations?

Back

A set of rules that determines the sequence in which calculations are performed in a mathematical expression.

What does PEMDAS stand for?

Back

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

Front

Solve: 6 + 4 x 2

Back

14 (First, multiply 4 x 2 = 8, then add 6).

Front

Solve: (3 + 5) x 2

Back

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

Front

What should you do first in the expression: 5 + 2 x (3 - 1)?

Back

Solve the parentheses first: 3 - 1 = 2.

Front

Solve: 90 - 5^2 x 3

Back

15 (First, calculate 5^2 = 25, then 25 x 3 = 75, and finally 90 - 75 = 15).

Front

What is the value of: (6 + 4)^2 x 3 - 3^2?

Back

291 (First, calculate (6 + 4) = 10, then 10^2 = 100, then 100 x 3 = 300, and finally 300 - 9 = 291).

Front

What is the first step in solving: 3 x 48 / (15 - 3)?

Back

Solve the parentheses first: 15 - 3 = 12.

Front

Solve: 20 ÷ 2 + (3 x 1)

Back

13 (First, calculate 20 ÷ 2 = 10, then 3 x 1 = 3, and finally 10 + 3 = 13).

Front

What is an exponent?

Back

A number that shows how many times to use the base in a multiplication.
