The Babylonian cuneiform method of recording quantities, approximately 5000 years old, is among the oldest numeral systems in existence.


The Egyptian method for recording quantitities is based on 10 with a symbol for 1, ten, and each successive power of ten. A distinct hieroglypic was used for each power of 10.

Who invented the modern number system

The Indians invented the modern number system. It is often called Arabic numerals because it came to Europe through the Arabs. But Arabs themselves call it as "HindSaa" meaning - "given by Hindus or Indians". The Persians copied the Indian number system and then passed it on to the Arabs. Then an Italian mathematician named Fibonacci traveled to Algeria to study. When he came back home, he brought the Indian numerals with him. He wrote about the system in his book "Liber Abaci.“. This system has been really used in Europe . Today it is the number system used by the whole world.
