Sai Kiran subtracts a 70-digit number from another in 60.05 seconds
It was a day of ambiguity for 26-year-old B. Sai Kiran.
He could not decide whether to exult over his newly set world record or to mope over the lapse of milliseconds in achieving the task he set about for.
Nevertheless, jubilations broke out as soon as this numerical prodigy, in his second attempt on Monday, successfully subtracted a 70-digit number from another in 60.05 seconds.
Sai Kiran, who set out to achieve it in one minute, fell short of his goal by five milliseconds, still scaling the heights of the world record successfully. Delegates from the Record Holders Republic, United Kingdom, declared on the spot his ‘Super Subtraction Feat' as a world record.
Sai Kiran, a trainer in Vedic Maths and Vedic Memory, failed in the first attempt though. Despite completing his task two seconds before the set time, he committed mistakes in the giant subtraction. He was allowed a second chance which led him to success.
The attempt being for a Guinness World Record, it was ensured that all digits except the first in the minuend are smaller than the corresponding digits in the subtrahend, thereby raising the complexity level of the calculation.
“I am going to use Nikhilam sutra from Vedic Mathematics which is based on the number 10,” Sai Kiran declared prior to the event, “Through my feat, I want to show the greatness of Indian Mathematics to the world.”
While the conventional subtraction is done from right to left, Vedic maths requires it to be done from left to right, he explained.
The event was organised by Institute of Memory Power and Calculation Techniques in association with Bala Sahithya Parishad. Video recording of the event will be sent for an entry into the Guinness Book of World Records, the organisers said.

Congratulations for making us proud to be Indians.Wish you good luck for more such feets.
Bravo!! Congrats Mr. Sai Kiran. I hope Bharat government takes note of
the power of Vedic Mathematics and starts planning to include in school
early. We are proud of you, vedic maths and our culture.
Congrats Mr Sai Kiran. I am proud to be Indian. Let us positively expect our Government to accept for Vedic Maths. All the Best.
Sadasivam.
Namaste Sai Kiran,
Hearty congratulations to you. Being a student of Vedic Mathematics
and living in Canada, where learning Mathematical table is also not
important, and the kids here never fail until they reach grade 12, it
is high time that the school system revisit the math curriculum and introduce Vedic Mathematics as one of the subjects to make it better
for the future generation.
Wish you all the best.
a great achievement by sai kiran ,it is high time we introduce Vedic
maths in our school syllabus, i wish him all the best.
Congrats Mr.Kiran.. You have made India proud by trying to achieve this feat. If we can introduce such type of techniques in our educational systems, the students will gain knowledge and can solve so many mathematical problems in their future... Would really like to appreciate your efforts and hard work behind this..All the best in future and hope to see some more new methods in Maths.
Congrats Mr. Kiran for achieving this marvelous feat. It is time we introduce vedic mathematics in to our regular mathematics curricula for school and college going children.
Bravo Bravo Sai Kiran...Proud of u and Indian Vedic Maths.,let the world know that India has a treasure of knowledge and maths is not a subject of problems it can be learnt with ease as v drink water...proud to be an Indian and of course India is proud to have young talented people like you let your fragrance spread all over the world,God bless you.
