In this activity, we will be answering short mental arithmetic questions which get progressively harder.

 

Try to do as much working in your head.

 

Remember some quick short cuts, such as:

 

1.  To multiply by 4, just double and double again.

2.  To find a quarter of something, just halve and halve again.

3.  To find 10% of something, just divide by 10.

 

Let's get started!
