How fast is your mental arithmetic? You certainly can not win her, Shakuntala Devi, the mathematician from India!

Shakuntala Devi was a child prodigy. She earned the 1982 edition of The Guinness Book of World Records for her talents. Shakuntala Devi, she just passed away this year (2013/4/21), at the age of 83 years old. Today's Google Doodle is used to honor and commemorate her.

When she was 6, she demonstrated her calculation and memorization abilities at the University of Mysore. Surprisingly, she was able to do this without any formal education.

Shakuntala Devi is really very powerful, also known as the world's most intelligent woman. She can calculate the product of two arbitrary 13-digit in 28 seconds. For the talents, she was called "Human Computer".

Do you want to calculate this multiplication?

"7,686,369,774,870 × 2,465,099,745,779 =?"

She correctly answered 18,947,668,177,995,426,462,773,730 in 28 seconds.

In her birthday that day, let us remember the world's most intelligent woman Shakuntala Devi.
