learning table of 9 in seconds.

This post is really interesting to write as we all must have struggled in our childhood while learning tables or youngs student must be ....as its tedious task to learn so many tables....so here we have some techniques or ways to solve tables in less time.

The First case.

The annexed table of products produced by the single digit multiplier 9 gives us the necessary clue to an understanding of the sutra:

The meaning of the sub corollary thus fits in smoothly I.e, that the multiplicand has to be decreased by 1 and as for the right hand side , that is mechanically available by the subtraction of the left hand side from 9 which is practically a direct application of the Nikhilam Sutra.

● 9 x 2

(2-1)/(9-(2-1))

1/9-1

1/8

18 answer.

● 9 x 3

(3-1)/9-(3-1)

2/7

27 answer.

The second case::

● 11 x 99

(11 - 1)/99-(11-1) = 1089

● 12 X 99

( 12-1)/99-(12-1)=1188

And so on.....

Keep learning keep smiling 😊😊
