Origin and History of Numbers
This session will help you that from the numbers where generated and what our lives be without numbers.
The Hindu-Arabic numerals were invented by mathematicians in India. Perso-Arabic mathematicians called them "Hindu numerals" (where "Hindu" meant Indian). Later they came to be called "Arabic numerals" in Europe, because they were introduced to the West by Arab merchants.
Note that currently we also use roman number system. Under the Roman system the numbers are written differently. V means 5, x for 10, I for one, C stands for a hundred, D stands for 500, M means a thousand L for fifty, X for ten, V for five and I for one.
But, there’s one problem in it. Since there is no symbol for zero in it, there is difficulty in carrying out addition, subtraction and other calculations.
For example. In the Arabic number system we can easily add 1025 and 205 however, the same calculation is not so easy, when it comes to the Roman system (just because we don’t have any symbol for ZERO).
Numbering systems came out of necessity of economic and social development, and therefore there are no differences between ancient rock paintings, memory aids (mnemonic devices), winter counts, tallies, knotted cords, hieroglyphs or the alphabet, these were all anatomies of necessary information storage and messaging.
