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 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

(−5)2 = +25 = (−5) × (−5)
