Ancient arabic method of multiplication

Hi friends, in this article am explaining the ancient Arabic method of multiplication. It is developed by Egyptian mathematicians.

eg:  32  *     29                             32

64   *    14

128   *     7                          128

256    *    3                          256

512     *    1                           512

Answer= (32 + 128 + 256 + 512) = 928

 

In the above example multiplying two numbers 32 and 29. The number 29 is odd , so the other side number 32 write to next column for adding. If the number is even ,then multiply the first number by 2  and second number divided by 2 . This process will repeat until the second number become 1.
