If Aryabhatta invented '0' in the 5th century, how do we know that Ravana had 10 heads?

We all know that Zero was invented by Indian mathematician Aryabhata. But it is believed that counting from 1 to 9 was discovered by the Arab people, which was inspired by the initial discovery in India. The number that is used worldwide today is called 'Arabic Numeral System' .

Now the question arises that when Aryabhata was invented Zero, then how did Ravana have 10 heads, Kauravas number 100 and how did Sahastraj have 1000 hands? 

Let's understand the mathematics behind this 

The number system existed long before in all civilizations including India, but was not zero then. During this time every number used to have a symbol. There were also different symbols for numbers from 1 to 10. Counts were written based on these symbols. 

'Brahmi script' 

In ancient India, 'Brahmi script' was widely used to write Sanskrit verses . There was also a number system from 1 to 10 under 'Brahmi Lipi'. There was no provision of zero in this script. Hardly any of us have read this script.

There are different symbols for counting from 1 to 10 under 'Brahmi Lipi' . In such a situation, if someone wants to write 11, then for this, the symbol of ten and the unit symbol have to be written together.

Sharda Lipi 

However, in the 'Sharada Lipi' number system developed in the third century, (0) was used instead of (.). It was similar to 'Devanagari script'.

Let us tell you that the numeral system was first seen in the ' Bakshali Manuscript' of the third century . During this time, the place of (0) (.) Was first added to the 'Bakshali Manuscript' and then it was also added to other scripts.

You must have understood by now that Ravana had 10 heads and why was the number of Kauravas 100?  

After this Aryabhata invented the void in the 5th century. During this period, Aryabhata invented zero instead of symbolic numbers and increased its importance so much that from 1 to 10 the number could not be completed without zero.
