Multiply any number by 11 in 3 seconds!! mental math trick


This technique teaches you how to multiply any

number by eleven, easily and quickly. 


We will take a few examples and from these you will see the pattern used and

also how easily they are to do.


So, to begin let's try 12 times 11. First things first you

will ignore the 11 for the moment and concentrate on the 12. 


1.Split the twelve apart, like so : 1+2

2.Add these two digits together 1+2 = 3

3.Place the number 3 in between the 12 to give 132


11x 12 = 132


Let's try another


 48 x 11


Again, leave the 11 alone for a moment and work with the 48


4+8=12


So now we have to put the 12 in between and 8, but don't do this: 4128 as that is wrong


First, do this: place the 2 from the twelve between the 4 and 8 giving 428.


Now we need to input the 1 from the twelve into our answer also, and to do this just add the one from 12 to the 4 of 428 giving 528!


Example 3) 65 x 11


Step 1:As mentioned above in the first step, focus on 65.


Split the number like this, 6 5


Step 2: Now add the two digits of 65 that is 6+5 = 11


Step 3: However, we cannot place 11 in the middle of the two digits of 65. 


Write 1 in between 6 and 5. 


Carry over the remaining 1 to the previous number 6 as given below:


615


715(6+1=7)


Add the 1 with 6 to get the digit in hundredth place.


We have arrived at the answer for, 65x11 = 715


Try multiplying 32 x 11 right now in your mind.
