22 divided by 2 makes 11 then take away 2 equals 9 or

3 power of 2 equals 9

22/2-2=9 or ((2/2)+2)2 =9

## Zoe thinks:

Here’s my answer for today’s Maths Challenge.

A way to make 8 could be: (22)+(2+2)=8

A way to make 9 could be: (22÷2)-2=9

The biggest number you can make is: 49,284 (2222)

The smallest number you can’t make is any number below -482, it could be -1,000,000,000,000,001 (minus A quadrillion and one) or -483 (minus four hundred and eighty-three)
