Divesh Shah

From Wikipedia, the free encyclopedia

Divesh R. Shah (born 1968) is an Indian mental calculator.

He can easily:

Multiply two 8 digit numbers in one step.
Add 20 digits in 5 seconds.
Square any 5 digit number.
Extract the square root of a 6 digit number in few seconds.

He loves teaching mathematics and has conducted Mental Calculation workshop for school children and the public in general in countries like the UK, USA, Germany, Singapore, Malaysia, Dubai, India, Sri Lanka and so on.

He came up with an idea of presenting the numbers to audiences in the form of a stage show named "The Maths Show", the first performance hit the Mumbai (Bombay) city at Zaverben Hall, Ghatkopar, on September 7, 1998. A modest attempt to popularize mental mathematics, "The Maths Show" has seen over 400 performances held all over the world till date.

With the show gaining popularity, Divesh was flooded with queries from eager parents to make mathematics interesting for their children. The parents wanted to learn more easy-calculating techniques for their children, which resulted in "The Maths Show-Part II" covering more topics and different techniques for calculating large numbers.
