Check out this cool math trick for the eleven times table. When you multiply a two digit number by eleven, simply add the digits of your number together and place the sum of the digits between the digits of your number. This works for two digit numbers where the sum of the digits is nine or less. For numbers where the sum of the digits is larger than nine just carry the one over to the tens digit. Challenge yourself by multiplying different two digit numbers by eleven.
