Order of Operations

Front

What is the order of operations in mathematics?

Back

The order of operations is a set of rules that determines the sequence in which calculations are performed. It is often remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What does PEMDAS stand for?

Back

PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.

Front

What is the first step in solving 3 + 4 x 6 - 4?

Back

The first step is to perform multiplication: 4 x 6 = 24.

Front

Calculate: 18 + (6 – 2) × 2.

Back

First, solve inside the parentheses: 6 - 2 = 4. Then multiply: 4 x 2 = 8. Finally, add: 18 + 8 = 26.

Front

What is the result of 7 x (7 - 4) ÷ 3?

Back

First, solve inside the parentheses: 7 - 4 = 3. Then multiply: 7 x 3 = 21. Finally, divide: 21 ÷ 3 = 7.

Front

What is the value of (6 + 5)?

Back

(6 + 5) = 11.

Front

In the expression 10 ÷ 2, what operation is being performed?

Back

Division.

Front

What is the result of 5 x 10?

Back

5 x 10 = 50.

Front

What do you do first in the expression 4 + 3 x 2?

Back

You perform multiplication first: 3 x 2 = 6.

Front

What is the result of 12 - 4 + 2?

Back

First, perform subtraction: 12 - 4 = 8. Then add: 8 + 2 = 10.
