You add the 2 numbers together and then divide by 2!

If you ever have to work out the average for a few numbers....you add them together and divide them by how many different numbers there are...

So for example:

The average of 15 and 31

15+31=46

46/2=23 is the average

the average of 2,8,9,11,16,15,23

2+8+9+11+16+15+23=84

84/7=12 is the average
