The following numbers can be put in numerous orders-

1 9 2 4 6 8 7

How many possible orders can that list of different numbers be put in different orders?

Here is an example: [remember to include this order in your guess]

9 1 2 4 6 8 7

*also- remember to include the FIRST set of numbers

7!

7 possible numbers for the first position

6 possible ..

... for the 7th position

Permutation of 7, taking 7 at a time:

P(7,7)=7!/(7-7)!=5040 ways
