Some of the contributions are: using base 10 symbols with placement value and using absolute value. This is due to Archimedes and Apollonius.

The Harappans used a decimal system to help with weights and measurements. You can goole the names above and get more information regarding other Indian accomplishements. (We are talking about east Indian's arent we?)

The peace and prosperity of the Gupta Empire enabled many advances.

• chess precursors Chaturanga and Shatranj arose during this period
