We continue the lessons of Counting. Today we will do basic counting of certain objects. Example 1: How many ways can you arrange the letters in the word: WORD. Lets see how to figure this question out. For the first letter, there are 4 possiblities, W, O, R or D. So 4 _ _ _ Now we have 3 left over: 4 3 _ _ And it continues to 4,3,2,1, which is 24. This is also known as factorials. 4! (!=factorial) =24 W-O-R-D W-O-D-R W-R-O-D W-R-D-O W-D-O-R W-D-R-O continued... Here ...

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!
