What is the Order of Operations?

Back

The Order of Operations is a set of rules that determines the sequence in which calculations are performed in a mathematical expression. The acronym PEMDAS helps remember the order: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Solve: -56 ÷ (-7) - (-3)

Back

11 (First, -56 ÷ -7 = 8, then 8 - (-3) = 8 + 3 = 11).

Solve: -8(2 - 5) ÷ (-4)

Back

-6 (First, solve inside the parentheses: 2 - 5 = -3, then -8 × -3 = 24, and 24 ÷ -4 = -6).

Solve: 5 - 6² ÷ 4 - 3

Back

-7 (First, calculate 6² = 36, then 36 ÷ 4 = 9, and finally 5 - 9 - 3 = -7).
