Sums and Differences

You may think that small numbers are easy. This game proves otherwise!

You work in pairs. One player selects two numbers between 1 and 10, works out (mentally) the sum and the difference and gives them to the other player. The other player then has to work out what the original two numbers were.

Sounds simple? Try it!
