  3. Hi,

    Do You know Shakuntala Devi,

    Shakuntala Devi was an Indian writer and mathematical wizard. She was popularly known as the “human computer” for making complicated calculations in her mind and effortlessly speaking out the results.


    India, a land famous for its contribution in the field of mathematics has always been proud of its mathematical prodigies and one such prodigy in recent times of modern India was Shakuntala Devi who was world-renowned & referred to as “Human-Computer.”
    Her exceptional abilities earned her a place in “The Guinness Book of World Records.”
