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 common acronym to remember this is 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: P - Parentheses, E - Exponents, MD - Multiplication and Division (from left to right), AS - Addition and Subtraction (from left to right).

Front

What is the first step in solving the expression: 6 + (2 x 3)?

Back

The first step is to solve the expression inside the parentheses: (2 x 3) = 6.

Front

Evaluate the expression: 5 + 3 x 2.

Back

The answer is 11. First, multiply 3 x 2 = 6, then add 5 + 6 = 11.

What operation do you perform first in the expression: 8 - 4 + 2?

Back

You perform the subtraction first: 8 - 4 = 4, then add 2 to get 6.

Front

Evaluate the expression: (10 - 2) x 5.

Back

The answer is 40. First, solve the parentheses: (10 - 2) = 8, then multiply 8 x 5 = 40.

Front

What is the result of the expression: 12 ÷ 4 + 3?

Back

The answer is 6. First, divide 12 ÷ 4 = 3, then add 3 + 3 = 6.

Front

Which operation comes first in the expression: 7 + 2 x (3 - 1)?

Back

The first operation is the one inside the parentheses: (3 - 1) = 2.

Front

Evaluate the expression: 3 x (4 + 2) - 5.

Back

The answer is 15. First, solve the parentheses: (4 + 2) = 6, then multiply 3 x 6 = 18, and finally subtract 5: 18 - 5 = 13.

Front

What is the value of the expression: 5 + 2 x 3 - 1?

Back

The answer is 10. First, multiply 2 x 3 = 6, then add 5 + 6 = 11, and finally subtract 1: 11 - 1 = 10.
