# Mathematics in Nepal

Mathematics in Nepal have been used for measurement since ancient times. Advanced mathematics were used primarily in the field of Astrology to predict position of planets to determine auspicious time for various Hindu rituals. In recent times, mathematics is taught formally in schools from primary level up to doctorate degree. All students must pass mathematics in the SEE exam.

## History

The history of mathematics in Nepal is inter-related with the history of mathematics in the Indian sub-continent. However, independent history of mathematics in Nepal also exists. The ancient Licchavi people developed a series of the system for measurement such as Kharika to measure land area and Kosh for measurement of distance. Similarly, Jayasthiti Malla, in 1350 AD standardized Mana and Pathi for volumetric measurement of grains and cereals.
The numerals of Ranjana script was developed in 199 BC. It was used until the mid-20th century in Nepal and India. It is still in use in the Newari language.

### Formal education

In the Rana Period, Kashi (Banaras) used to be the education hub to learn astrology and mathematics. The mathematics was based mainly on the text of Baskaracharya's Siddhant Siromani.
The formal education of mathematics in school started after overthrowing of Rana regime and start of democracy.
The M.A./M.Sc. in Mathematics started on July 14, 1959, and Central Department of Mathematics was formed on September 20, 1959, A.D. in Tripureshwor Bengali mathematician Prof. Asutosh Ganguli was the first head of Department in Master level mathematics courses at Tri-Chandra College.
