What is the Order of Operations?

Back

A set of rules that tells us the correct sequence to evaluate 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

Solve: 5 + 3 x 2

Back

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

Front

Solve: (8 - 3) + 2

Back

7 (First, subtract 8 - 3 = 5, then add 5 + 2 = 7).

Front

What do you do first in the expression 4 + (6 - 2) x 3?

Back

First, solve the parentheses: 6 - 2 = 4.

Front

Solve: 10 - 2 x 3

Back

4 (First, multiply 2 x 3 = 6, then subtract 10 - 6 = 4).

Front

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

Back

15 (First, solve the parentheses: 3 + 1 = 4, then multiply: 2 x 4 = 8, finally add: 7 + 8 = 15).

Front

Solve: (5 + 5) x 2

Back

20 (First, add: 5 + 5 = 10, then multiply: 10 x 2 = 20).

Front

What is the value of 12 ÷ (2 + 4)?

Back

2 (First, solve the parentheses: 2 + 4 = 6, then divide: 12 ÷ 6 = 2).

Front

Solve: 3 x (4 + 2) - 5

Back

13 (First, solve the parentheses: 4 + 2 = 6, then multiply: 3 x 6 = 18, finally subtract: 18 - 5 = 13).
