I have been running maths clubs for children completely free. In my building in Bangalore, I conduct maths clubs for several months, and every child who attended the club was poor in mathematics and is now showing brilliant results.

I was performing at a New Jersey high school, and I asked a class of 2,000 students, 'How many of you love mathematics?' and only one hand went up. And that was the hand of the maths teacher!

I have written a book called 'In the Wonderland of Numbers.' It's about a young girl, Neha, who is very poor in mathematics, but in a series of illusory experiences, she becomes a great mathematician.

I haven't had any formal education. Through the grace of god, I am gifted in mathematics and the English language.

I have a particular affection for zero because it was some of my countrymen who first gave it the status of a number.
