"Oldest Carved Zero"

So here is "Chaturbhuj temple"  excavated in a rock face in the Gwalior Fort, Madhya Pradesh by Alla, the son of Vaillabhatta & the grandson of Nagarabhatta of the Gurjara-Pratihara dynasty.

Thanks to an inscription in the sanctum we know that it was constructed in the year 876 AD. It is this inscription that also contains one of the earliest known uses of the mathematical zero. India is where the decimal numbering system based on position was invented.

The Romans had letters to represent numbers, the largest being M which represented 1,000. So if you wanted to indicate 10000 in Roman numerals you would wright MMMMMMMMMM - a cumbersome system, prone to errors! India created a system where the place of the number determine...

What it's value is. There are 2 e.g. of the use of zero on the inscription in the sanctum, located to the left of a now damaged Vishnu idol. We'll only able to successfully identify one of the zeros.
Here is Vishnu in the sanctum.
The inscription containing 0 in the background.

The inscription inside the Temple, the number “270” circled in red.
The inscription records the date as 876 AD.
Inscription -
“Om. Adoration to Vishnu! In the year 933 [876], on the second day of the bright half of the month of Magha the whole town gave to the temple which Alla,

the son of Vaillabhatta, had caused to be built a piece of land 270 hastas in length and 187 hastas in breadth, for a flower garden the town gave in perpetual endowment for a daily gift of 50 garlands of flowers.”

Hasta is a traditional unit of India to measure the length ...

.. From the elbow to the tip of the middle finger articles about 8 inches or 45 cm.

See guys that how similar the numbers looked to how 270 written today.

While there was an understanding of nothingness in the ancient Babylonian & Chinese culture.
It was in India that mathematicians put a symbol, the circle for it. The Babylonians used a marker to re present it, the Chinese used the space to represent nothingness.
