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.
