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

Calculate: 3 + 5 x 2

Back

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

Front

Calculate: (8 - 3) x 4

Back

20 (First, subtract 8 - 3 = 5, then multiply 5 x 4).

Front

Which operation is performed first in the expression: 10 + 2 x 3?

Back

Multiplication (2 x 3 = 6, then add 10).

Front

Calculate: 6 + 2 x (3 + 1)

Back

14 (First, solve inside the parentheses: 3 + 1 = 4, then multiply 2 x 4 = 8, finally add 6 + 8 = 14).

Front

What is the result of: 12 ÷ 4 + 5?

Back

8 (First, divide 12 ÷ 4 = 3, then add 3 + 5 = 8).

Front

Calculate: 5 x (2 + 3) - 4

Back

21 (First, solve inside the parentheses: 2 + 3 = 5, then multiply 5 x 5 = 25, finally subtract 25 - 4 = 21).

Front

What is the first step in solving: 7 + (6 x 2)?

Back

Solve inside the parentheses (6 x 2 = 12, then add 7 + 12 = 19).

Front

Calculate: 15 - 3 + 2 x 4

Back

19 (First, multiply 2 x 4 = 8, then subtract 15 - 3 = 12, finally add 12 + 8 = 20).
