Do you know your 11 times table?

Here's a great trick to play that my secondary school maths teach er taught us (as long as you are reasonable at maths).

Tell someone you can multiply 2 digit numbers by 11 faster than they can do it on a calculator.

Get a third person to call out numbers. Lets say they say 43 x 11.

Add the two numbers together and put that number in the middle:

4 + 3 = 7 -------> 4 3 7

43 x 11 = 437! Easy. So all you have to do is add the numbers and put it in the middle!

NOTE: It gets a little harder if the numbers add up to more than 9! Lets say they say 57...

5 + 7 = 12... put the two in the middle, and add 1 to the first number aswell. 627. See it? Easy.

Enjoy!!! Let me know if it worked!
