In addition to the application of astronomy to plot the seasons for agricultural purposes, India developed coinage based on weights and measures for trading purposes. (Dani, 2016.) It also developed the concept of zero as well as the decimal system. Although the use of the latter does date back to the Babylonians, India developed it further for practical purposes.  The rudiments of algebra were imported from India via the Middle East as were aspects of geometry.   Perhaps the most long-lasting achievement of India during this period was in the creation of ordinal numbers from 1 to 9. These numbers which form the basis for numeracy today were originally called Indian numerals. When transferred to the Middle East and then to Europe, they were named as Arabic numbers. This export from India to the rest of the world has had an enormous effect on commerce and business everywhere. Notably, as a replacement for the cumbersome Roman numeral system, it facilitated the rise of central procedures in other civilizations, for example, the emergence of transactions such as double-entry book-keeping in the West.
