Multiplying a number by 11 is incredibly easy -
astonish your parents and friends with this.


To multiply any 2-figure number by 11 we just put
the total of the two figures between the 2 figures.

  • 26 x 11 = 286



    Notice that the outer figures in 286 are the 26
    being multiplied.

    And the middle figure is just 2 and 6 added up.

  • So 72 x 11 = 792
