Question from kirk, a parent:

The sum of two numbers is 63. The difference between the numbers is less than 10. Find all possible pairs.

Hi Kirk,

I can get you started. You want the two numbers to be close together. If they were equal then each would be 63/2 = 31.5. I don't expect you want fractions so take half from one and give it to the other to get 31 and 32.
