Worksheet Overview

In this worksheet, you must use the brackets buttons on your calculator.

Remember

The top and the bottom must go in brackets, so that:

7 + 3

5 × 2

(7 + 3)

(5 x 2)

= 1

The order of operations is

1. brackets

2. powers or indices

3. multiplication and division

4. adding and substraction

3 × 4² = 3 × 16 = 48

and (3 × 4)² = 12² = 144

−5² = −25 = (−(5 × 5))

(−5)² = +25 = (−5) × (−5)
