Shakuntala Devi was a mathematician who cherished to simplify the magic of arithmetic calculations through her exceptional talent. Her wisdom and gifted personality have inspired millions of students all around the globe.
Shakuntala Devi was born on 4th November 1929 in Bangalore, Karnataka. She had unparalleled talent in calculating complex mathematical numbers. She proved her exceptional talent in arithmetic maths through her math shows worldwide at a very tender age.
Devi’s parents lived in Bangalore and belonged to a Kannada Brahmins community. At the tender age of 3, Devi’s father, Mr. Sudhararaja Rao, discovered her mathematical talent during a card trick. Later, he took Devi for roadshows to demonstrate her mathematical skills in schools and colleges. As a young girl, she was participating in maths shows, supporting her family by answering “tough-as-nuts” questions.
At the age of 6, Devi performed her arithmetic skills at the University of Mysore. She achieved this without any formal education as her parents couldn’t afford to send her to school.
People who attended her shows would randomly ask her numbers to calculate or find the day with the date provided. Her answers were always perfect and faster than they would expect. Many people at the top universities wondered, “How Shakuntala Devi Calculates?”.
In 1960, she married Paritosh Banerjee and was blessed with a daughter, whom she raised herself after she discovered that her husband was gay.
Why is Shakuntala Devi Famous?
Most of the time, people were astonished by Devi’s mathematical excellence. People were always thinking about how Shakuntala Devi calculated such huge numbers randomly assigned to her in an instant. She was an extraordinary human with impeccable calculating skills that brought her the title “Human-Computer.”
On 18th June, 1980 at Imperial College London she demonstrated multiplication of two complex 13-digit numbers such as 7,686,369,774,870 * 2,465,099,745,779.
Those numbers were given randomly, and Devi answered it as 18,947,668,177,995,426,462,773,730 in just 28 seconds, it has brought her worldly fame. She never used any paper or pen to calculate the numbers; she used her mental ability to determine the right answer in her calculations.
The independent will to achieve the success and enjoyment in the subject of maths earned her universal recognition. She believed that our determination to grasp and follow the greater good in our interests makes us a successful person. She felt that embarking on a smart path through difficult situations and assessments can make each of us an excellent student.

First, a Joke:
Why was the student confused when he went from English class to math class?
Because he was taught that a double negative in English is bad, but in math, it’s a positive.
Second, a Song:
Shakuntala Devi, India’s foremost female mathematician, was renowned for her super fast mental calculations. Also called “The Human Computer”, her achievements are often used as an example to highlight women in the STEM fields. In 1977, she famously found the 23rd root for a 201-digit number in 50 seconds. A few years later, in 1980, Shakuntala Devi was named in the Guinness Book of Records for the “Fastest Human Computation”. But mathematics was not her only love. She had diverse interests that defined a colourful and intriguing life.
