EASY MULTIPLICATION BY ELEVEN.
To multiply any two figures very quickly by eleven, all you need to do is to separate the figures and place their sum between them.
For example: 24 x 11 —264, the middle figure (G) being the sum of the 2 and 4. . Should the sum reach a double figure number, put the unit of the number in the middle position, and carry the one to the first figure.
