**Aryabhatiya**, Aryabhata has summarized mathematics, as known at that time, in 499 verse couplets or slokas. - The book
**Aryabhatasidhanta**was a handbook for day-to-day astronomical calculations. Some astronomical calculations are even today for preparing almanacs (panchangs).

**Other important books are:**
