The 11 trick My Way
Ho Hum boring

Actually I am going to use most of the same graphics, but these won't move.

Trust me the slide show is more fun

With 27 x 11 what this is supposed to show is that you separate the 2 and the 7 (from the 27) 
Add those digits together and put the sum ( 9) in the middle of the two numbers

11

Now what if the two digits add up to more than 9 you ask?

 

11
 

Ok thats the presentation my way.  I have a powerpoint presentation that much prettier that I will put up soon.
