Magic Mathematics -11th Rule

Maths is no more a difficult task. Just by following steps you can directly write down the answer to any number multiplied by 11.



·    Take for example the number 51236 X 11.

·    First, write down the number with a zero in front of it.

051236

·    The zero is necessary so that the rules are simpler.

·    Look at the 6 in the "units" position of the number. Since there is no number to the right of it, you can't add to its "neighbor" so just write down 6 below the 6 in the units place.

051236

          6

·    For the "tens" place, add the 3 to the its "neighbor" (the 6). Write the answer: 9 below the 3.

051236

        96

·    For the "hundreds" place, add the 2 to the its "neighbor" (the 3). Write the answer: 5 below the 2.

051236

      596

·    For the "thousands" place, add the 1 to the its "neighbor" (the 2). Write the answer: 3 below the 1.

051236

    3596

·    For the "ten-thousands" place, add the 5 to the its "neighbor" (the 1). Write the answer: 6 below the 5.

051236

  63596

·    For the "hundred-thousands" place, add the 0 to the its "neighbor" (the 5). Write the answer: 5 below the 0.
051236

563596

That's it ... 11 X 051236 = 563596
