**COUNTING**

So you say you know how to count?

You know, 1,2,3,4...

What if I were to ask you, how many numbers from 1 to 10?

Obviously 10 right?

How about if I ask you how many numbers from 8 to 17?

Is it 9?

noooo

You feverishly count on your fingers and triumphantly say 10!!!

Whats a fast way to do this?

Well there are two ways:

1) 17-8=9 9+1=10 (becuase of inclusives)

Or a slicker way:

2) 8-7=1, 17-7=10 We know 1 to 10, thats just 10!
