Managing Multiplication by Eleven

Updated on April 30, 2015


Multiplication by 11 is so easy to do


keep reading along and let me teach you


11 times any 2 digit number for example 26


Is the problem I'll first show you how to fix


Take the 2 and the 6 and add them together for 8


Stick 8 in between and your product is great !


Yep 286 is the correct sum


But, wait cause we are not done


Suppose you are factoring 11 times 85


Total of 8 plus 5 is 13 you arrive


3 still in the middle and 1 adds to 8


Practice on paper what here I state


8 plus 1, 3 in the middle then 5


The correct answer is 935 !


This math trick works factors 11 to 99


Try it with all, you'll see it's divine !


Remember this is only for number 11s use


Tried on any other number leads only to abuse.
