Worksheet Overview

In this activity, we will be using our mental maths skills to solve a very specific problem!

 

You need to get thinking a little outside the box for this one.   

 

For each question, you need to select alternative ways of carrying out the given calculations because the '5' key is broken on your calculator.

Example

Work out   567 + 45

 

Answer

We could, for example, work out    467 + 100 + 44 + 1
