    Benjamin makes numbers dance. In his day job, he's a professor of mathematics at Harvey Mudd College; in his other day job, he's a "Mathemagician," taking the stage to perform high-speed mental calculations, memorisations and other astounding mathematic stunts. It's part of his drive to teach math and mental agility in interesting ways, following in the footsteps of such heroes as Martin Gardner.

    This is by "Vedic Maths", search or Google about it, you can find videos on youtube too about, you can multiply, divide, square numbers, find square root , cube roots, solve system of simultaneous equations, do calculus , without writing and just calling out.
    This was the ancient mathematics of India too. You need far less calculations and simple tricks.
