Worksheet Overview

QUESTION 1 of 10

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)
