IMPRESS YOUR PARENTS

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
