BACK TO WORKSHEETS
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
Can you see what we had to do here? Create a calculation that removed the number 5 from it.
Let's give it a go and see how you get on.
