Formula 2

s 100. Now follow the rules, 92 is 8 less than base 100. And 86 is 14 less than the same base 100. Hence 8 and 14 are called deviations from the base.

ii.   When both the numbers are higher than the base.

Here the deviation is positive as the numbers are higher then base.

We consider 03x07=21. This is done because, we need to consider two digits in deviation as it the base 100 has two zeros. If the deviation is near 1000 then we need to consider 3 digits in the deviation (e.g., 004 and not just 4).

iii. One number is more and the other is less than the base.

In this situation one deviation is positive and the other is negative. So the product of deviations becomes negative. So the right hand side of the answer obtained will therefore have to be subtracted.

12/ (-8) =112 how?

12/ (-8) should be read as 'one two, eight bar'. Here 'one' and ' two ' are in normal form. ‘Eight' is in complement form (परम मित्र रुप में). So, when we bring a carry from normal form to complement form, '12' becomes '11' and 'eight bar' becomes '2'( complement of 8). Hence 12/ (-8) =112.
