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 the order of operations?

Back

The first step is to solve expressions inside Parentheses.

Front

What is the second step in the order of operations?

Back

The second step is to calculate Exponents.

Front

What should you do after solving Parentheses and Exponents?

Back

After solving Parentheses and Exponents, perform Multiplication and Division from left to right.

Front

What is the last step in the order of operations?

Back

The last step is to perform Addition and Subtraction from left to right.

Evaluate: 5 + 3 × 2

Back

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

Front

Evaluate: (8 - 3) × 2

Back

The answer is 10. (First, solve inside the parentheses: 8 - 3 = 5, then multiply 5 × 2 = 10.)

What is a base in an exponent?

Back

The base is the number that is multiplied by itself when raised to a power. For example, in 2³, 2 is the base.

Evaluate: 4² + 3 × 2

Back

The answer is 19. (First, calculate 4² = 16, then 3 × 2 = 6, and finally 16 + 6 = 22.)
