General History/numbers in india
When was international numerals viz. 1,2,3...introduced in India. Whether it was introduced after the invasion of British?.
How was the numbers written in India and how business was undertaken before its introduction, as there are several regions with their own languages and their own scripts. How maths subject was taught during that time i.e. before introduction of international numerals.
Arabic numerals originated in India. The following excerpt may be of interest:
"The question nevertheless remains why Indians dropped their own multiplicative system and introduced the place-value system, including a symbol for zero. We currently don’t know for sure. Victor J. Katz elaborates in his fine A History of Mathematic, Second Edition:
“It has been suggested, however, that the true origins of the system in India may be found in the Chinese counting board. Counting boards were portable. Certainly, Chinese traders who visited India brought them along. In fact, since southeast Asia is the border between Hindu culture and Chinese influence, it may well have been the area in which the interchange took place. Perhaps what happened was that the Indians were impressed with the idea of using only nine symbols, but they took for their symbols the ones they had already been using. They then improved the Chinese system of counting rods by using exactly the same symbols for each place value rather than alternating two types of symbols in the various places. And because they needed to be able to write numbers in some form, rather than just have them on the counting board, they were forced to use a symbol, the dot and later the circle, to represent the blank column of the counting board. If this theory is correct, it is somewhat ironic that Indian scientists then returned the favor and brought this new system back to China early in the eighth century.” http://www.brusselsjournal.com/node/4107
