Got it yet?
If you took longer than 28 seconds, then you missed your chance at breaking a world record held by Shakuntala Devi. The woman known as the "human computer" died in April, and Monday would have been her 84th birthday.

The story says of Devi:
"Devi is a sari-clad diva of numbers, a math prodigy who can calculate as fast and accurately as any hand-held contraption. She is one of those rare people who somehow -- even she does not know how -- possesses a skill with figures that amazes computer wizards, intrigues academics and dumbfounds those of us who have difficulty balancing checkbooks."
(Note: the story pegs her age as 43, but that was probably off by a couple of decades. She was born in 1929.)
