How does Shakuntala Devi calculate so fast?
* Cube roots: It began with extracting cube roots of large numbers, which she could do in her head rapidly while still a child in the 1930s. This means that 46,295 multiplied by itself seven times yields that number of 27 digits; Shakuntala Devi worked backwards from the 7th power to derive the root.
How did Shakuntala Devi learn mathematics?
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.
Is Shakuntala Devi The fastest mathematician?
1. Devi holds the Guinness World Record for “Fastest Human Computation.” In 1980, she correctly multiplied two 13-digit numbers in just 28 seconds at Imperial College London. The feat, also included in her obituary, earned her a place in the 1982 edition of the Guinness Book of World Records.
Did Shakuntala Devi contribute to mathematics?

What is Aryabhatta formula?
A simple Diophantine equation would be ax + by = c. In this equation a, b and c are given integers; and x and y unknown integers. Aryabhatiya is the earliest known work which examines integer solutions to Diophantine equations of the form by = ax + c and by = ax – c.
