Students may have mixed feelings about the subject of mathematics. While some people like the challenge of solving tricky equations, others need help understanding their complexities. Vedic Maths, a methodology drawn from the Vedas, ancient Indian texts, offers a unique way of problem-solving in mathematics.
The ‘Sesanyankena Caramena Sutra‘ stands out among its numerous sutras (aphorisms) for its effectiveness and simplicity.
We’ll examine this sutra by going through an example:
Express 1/7 as a decimal
1. Add ‘zero’ to the numerator, which makes 1 as 10
2. If the numerator is less than the denominator, add another ‘zero’; else, proceed as follows.
3. Divide : (10)/7 = 1 remainder 3
4. Adding zero to the remainder (since it is less than the denominator), we divide as (30)/7= 4 remainders 2
5. We continue taking the remainder the following the steps from the start as follows :
(20) /7 = 2 remainder 6
(60) /7 = 8 remainder 4
(40) /7 = 5 remainder 5
(50) /7 = 7 remainder 1
6. Now note that the remainder is ‘1’, the same as the numerator ‘1’.This means we would get the repetition of the answers again and again. So we will stop here.
7. Using the numbers(remainders) 3,2,6,4,5,1 got above, we multiply them with the denominator ‘7’,
7 x 3 = 2 1
7 x 2 = 1 4
7 x 6 = 4 2
7 x 4 = 2 8
7 x 5 = 3 5
7 x 1 = 7
8. Now we take the red shaded numbers from the above steps as sequence,142857 (which would be our final Result)
Therefore, Result (1/7) = 0.142857142857
With its wealth of sutras, Vedic mathematics provides many techniques for simplifying mathematical calculations. The Sesnyankena Caramena Sutra, or “The Remainder by the Last Digit,” is an excellent example of how these ancient mathematical ideas are still valuable and relevant today. By utilizing the power of this sutra, students can speed up their calculations, develop their mathematical confidence, and discover the joy of problem-solving.
