Decimal system- the Gupta came up with the decimal system. The system of tens, hundreds, thousands, and so on. This also contains the decimal places, like the tenths, hundredths, and thousandths.
Even though they are called "Arabic" Numerals, the Guptas were the ones that actually came up with this number system.
Along with a number system, the Guptas invented the idea of "zero". This was the idea of having a value or symbol for nothing.
