Here we will learn the Vedic sutra ‘By the deficiency’ which means how less or more the number is from the base number. The base number as explained earlier is 10 or a multiple of 10.
7 is deficient by 3 from 10
8 is deficient by 2 from 10
29 is deficient by 1 from 30
97 is deficient by 3 from 100
Base and Complement are very important in Vedic Mathematics and form the basis of many calculations.
As explained above we work in a base 10 number system. In order to ease our calculations we can take any number ending with ‘0’ i.e. any multiple of 10 as our base.
The Complement of a number is the difference between that number and the next higher power of 10.
This includes all 1 digit numbers. It is the number that should be added to make it 10.
The complement of 6 is 4.
The complement of 7 is 3.
This includes all 2 digit numbers. It is the number that should be added to make it 100.
The complement of 55 is 45.
The complement of 89 is 11.
