Recently I have been reading this book called Vedic Mathematics or sixteen simple mathematical formulae from the Vedas by late Jagadguru Sarikaracarya
Sri Bharati Krsna Tlrtha Maharaja ji
and learned some simple mathematical techniques to simplify calculations. I want to share this knowledge so here I am showing you the process of multiplication.
The Sutra: reads : (Nikhilam Navatascaramam Dasatah) which, literally translated, means;
“all from 9 and the last from 10”!
Suppose we have to multiply 9 by 7.
(i) We should take, as Base for our calculations, that power of 10 which is nearest to the numbers to be multiplied
(ii) Put the two numbers 9 and 7 above and below on the
lefthand side.Subtract each of them from the base (10) and write
down the remainders (1 and 3) on the right-hand side with a connecting minus sign (—) between them,to show that the numbers to be multiplied are both of
them less than 10.
(iii) The product will have two parts, one on the left side
and one on the right. A vertical dividing line may be
drawn for the purpose of demarcation of the two
parts.
Subtract the base 10 from the sum of the given no. (9 and 7 i.e. 16). And put (16–10) i.e. 6, as the left-hand part of the answer.
