EARLY LIFE
EARLY LIFE OF SHAKUNTALA
Shakuntala Devi was born in 4 November 1929 at Bangalore, Karnataka to a Kannada Brahmin family. Her father, C V Sundararaja Rao, worked as a trapeze artist, lion tamer, tightrope walker and magician in a circus.
He discovered his daughter's ability to memorise numbers while teaching her a card trick when she was about three years old. Her father left the circus and took her on road shows that displayed her ability at calculation. She did this without any formal education. At the age of six she demonstrated her arithmetic abilities at the University of Mysore.

HER MENTAL CALCULATION
MENTAL CALCULATION OF SHAKUNTALA
Devi travelled to several countries around the world demonstrating her arithmetic talents. She was on a tour of Europe throughout 1950 and was in New York City in 1976. In 1988, she travelled to the US to have her abilities studied by Arthur Jensen. Jensen tested her performance at several tasks, including the calculation of large numbers. One of the problems presented to Devi included calculating the cube root of 61,629,875 and the seventh root of 170,859,375 Jensen reported that Devi provided the solution to the problems before Jensen could copy them down in his notebook. In 1977, at Southern Methodist University, she gave the 23rd root of a 201-digit number in 50 seconds.
Her answer, which was 546,372,891, was confirmed by calculations done at the US Bureau of Standards by the UNIVAC 1101 computer, for which a special program had to be written to perform such a large calculation, which took a longer time than for her to do the same. On 18 June 1980, she demonstrated the multiplication of two 13-digit numbers – 7,686,369,774,870 × 2,465,099,745,779. These numbers were picked at random by the Department of Computing at Imperial College London. She correctly answered 18,947,668,177,995,426,462,773,730 in 28 seconds. This event was recorded in the 1982 Guinness Book of World Records. Shakuntala Devi explained many of the methods she used to do mental calculations in her book Figuring.
