Times 11 trick

If someone gives you a question like 63 times 11.
The first number will always be the same 6.
Then you add 6 plus 3 = 9 and then the 9 will be your middle number. Then the last number will always be the same as well 3.
So your answer is 693

  1. Did you come up with this yourself? This is a much better way to add up 11 with something.
