MS. Shakuntala Devi was an Indian mathematician known as the "human computer" for her ability to perform complex calculations at incredible speeds without the use of any mechanical devices. Some of her achievements include solving the 23rd root of a 201-digit number in 50 seconds in 1977. She also multiplied two randomly selected 13-digit numbers in 28 seconds, beating a computer. Devi authored several books and received various awards recognizing her talents, but passed away in 2013 at the age of 83.

3. MS.SHAKUNTALA DEVI –INDIAN MATHEMATICIAN
Very few people around the world achieved
what this wonder-woman did. A mathematical
prodigy, also known as the 'human computer',
MS.SHAKUNTALA DEVI was known for her
complex problem-solving skills without the aid of
any mechanical device.

4. BIRTH AND FAMILY BACKGROUND
 MS.SHAKUNTALA DEVI is a calculating prodigy
who was born on November 4, 1939 in Bangalore,
India. She was born in a kannada orthodox family.
 Her father refused to become a priest and instead,
wanted to entertain others as a tight-rope walker. He
thus became a circus artist and 3-year-old
MS.SHAKUNTALA used to accompany him to the
circus and often come back mesmerized with her
interesting card tricks that initiated her love for
numbers.

5. CHILD PRODIGY
 News of her ability to solve difficult
mathematical problems soon spread like
wildfire. By the age of 6, she had her first major
show at the University of Mysore where she
displayed her mathematical prowess by finding
out complex square roots and cube roots within
a few seconds. After a few more similar
performances, she found success at Annamalai
University at the age of 8, when she was finally
acknowledged as a 'child prodigy’.

7. PERSONAL LIFE
 In 1944, she moved to London with father. After
returning India in 1960’s ,she got married to paritosh
banerji, an officer of the Indian Administrative
Service from Kolkata. They were divorced in
1979. DEVI returned to Bangalore in the early 1980s.

8. ACHIEVEMENT
 In 1977, at Southern Methodist University, she
was asked to give the 23rd root of a 201-digit
number; she answered in 50 seconds. Her
answer—546,372,891—was confirmed by
calculations done at the U.S. Bureau of
Standards by the UNIVAC 1101 computer, for
which a special program had to be written to
perform such a large calculation.

9. ACHIEVEMENT
 On June 18, 1980, she demonstrated the
multiplication of two 13-digit numbers—
7,686,369,774,870 × 2,465,099,745,779—picked at
random by the Computer Department of Imperial
College, London. She correctly answered
18,947,668,177,995,426,462,773,730 in 28
seconds This event is mentioned in the
1982 Guinness Book of Records. Writer Steven
Smith states that the result is "so far superior to
anything previously reported that it can only be
described as unbelievable". She was popularly

 Her name was listed in the '1995 Guinness Book of World
Records' edition for her outstanding mathematical feat
where she beat the world's fastest computer at
multiplying two thirteen digit numbers.
 A month before her death, she was honored with the
'Lifetime Achievement Award' in Mumbai, in 2013.

12. MAJOR WORKS
 'Puzzles to Puzzle You' is considered one of
MS.SHAKUNTALA DEVI's best works for
aspiring and budding mathematicians. Critics
have rated this book as one of the best reads
for people who want to excel in the field of
mathematics and master the secrets of the
subject. A book meant for starters, this
publication sold over 6,000 copies in its first
week and continues to be an inspiration for

included in the 'Top 100 books by Indian
authors' in 2005.

18. THE TALENT OF MS.SHAKUNTALA DEVI
 This famous Indian mathematician and 'Child
Prodigy' never attended school in her younger
days, but grew up to become one of the greatest
mathematicians and authored a number of
books on mathematics.
 In Rome, a calculating machine found one of
her answers to be wrong. However, after re-
checking the answer, the solution given by the
computer was proven wrong and hers was
