Mongolian numerals

The main sources of reference for Mongolian numerals are mathematical and philosophical works of Janj khutugtu A.Rolbiidorj (1717-1766) and D.Injinaash (1704-1788). Rolbiidorj exercises with numerals of up to 10⁶⁶, the last number which he called “setgeshgui” or “unimaginable” referring to the concept of infinity. Injinaash works with numerals of up to 10⁵⁹. Of these two scholars, the Rolbiidorj’s numerals, their names and sequencing are commonly accepted and used today, for example, in the calculations and documents pertaining to the Mongolian Government budget.
