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 acronym PEMDAS helps remember the order: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What does 'squared' mean in mathematics?

Back

'Squared' means raising a number to the power of 2. For example, 3 squared (3²) is 3 x 3 = 9.

Front

Evaluate: 5 + 3²

Back

5 + 3² = 5 + 9 = 14.

Front

What is an exponent?

Back

An exponent is a number that shows how many times a base is multiplied by itself. For example, in 2³, 2 is the base and 3 is the exponent, meaning 2 x 2 x 2.

Front

Evaluate: (4 + 2) x 3

Back

(4 + 2) x 3 = 6 x 3 = 18.

Front

What is the result of 6²?

Back

6² = 6 x 6 = 36.

Front

Evaluate: 10 - (2 + 3) x 2

Back

10 - (2 + 3) x 2 = 10 - 5 x 2 = 10 - 10 = 0.

Front

What does the term 'cubed' mean?

Back

'Cubed' means raising a number to the power of 3. For example, 2 cubed (2³) is 2 x 2 x 2 = 8.

Front

Evaluate: 3 x (2 + 4) - 5

Back

3 x (2 + 4) - 5 = 3 x 6 - 5 = 18 - 5 = 13.

What is the value of 2² + 3²?

Back

2² + 3² = 4 + 9 = 13.
