# Math: An Indian Tradition (I)

Our country is a scientifically promising country. Historically, Indians have invented the number system, algebra, trigonometry… in one word: Math. We had incredible talent in India and we are sure that your child is one of them. Now, discover more about our heritage.

The Number  “0” :

The concept of zero first appeared in India during the 5th Century. “The earliest recorded usage of a circle character for the number zero is usually attributed to a 9th Century engraving in a temple in Gwalior in central India.” The sign 0 for use in any religious texts; it embodied infinity and emptiness.

During the 7th century, the number 0 became a mathematical number. Brahmagupta, a great Indian mathematician and astronomer, established for the first time the basic mathematical rules for dealing with zero; however his understanding of division by zero was incomplete (he thought that 1 ÷ 0 = 0).

Chess and Math :

Chess is one of the oldest intellectual games in the world and was invited in India during the VIth century.

A legendary Brahmin, Sessa, created chaturanga, chess ancestor, in order to distract his prince while demonstrating the weakness a King without company. Wishing to reward Sissa, the prince told him to ask for anything he desired. Sissa just replied: “Please put a grain of wheat on the first square of the chessboard, two on the second square, four on the third and eight on the fourth…. That is to say, double wheat grains for every next square till the 64th square, i.e. the last one. ” At first, this wish seemed very easy to fulfill, but the prince could not provide enough grains to give the Vizier a chessboard’s worth of grains. 5 000 foams would be necessary in order to reward Sessa.
