There is some controversy about the idea that the decimal system was invented in India. This should be no surprise because people like to argue over things like this.
The decimal system may have originated in the Gupta Empire.
Arguably, any peoples that used to count on their fingers used the decimal system.
Note:
Do not confuse the decimal system with the Arabic numeral system!
Both Ancient Romans and Arabs had decimal systems; but Roman numerals were hopeless for mathematics and accounting; whereas Arabic numerals are used universally today.
The decimal system refers to counting in tens and powers of tens and this system was used when Australia was colonised by Britain in 1788. Decimal coinage was introduced much later - in 1966.
The first mathematician is Arya bhatt.
On 14 February 1966, decimal currency was introduced in Australia, replacing the British system of pounds, shillings, and pence with dollars and cents. This change simplified the country's monetary system and brought Australia in line with other nations using the decimal currency system.
The oldest known text to use a decimal 0 is an Indian document: Lokavibhâga, dated 458 AD.
Abu Ja'far Muhammad ibn Musa Al-Khwarizmi
he did not invent nor learn it he introduced it to the united states
It is believed that decimals were introduced to the Egyptians in around 1300 ad. The system is based on ten because humans have ten fingers.
Because they needed something to represent nothing, so came up with 0.
Australia's currency went decimal on 14th February, 1966. The decimal system is easier to use than others because it based on 10. The old Imperial monetary system was based on the old English system where there were 12 pennies in a shilling and 20 shillings in a pound or, 240 pennies in a pound. Australia's system of weights and measures went metric for the same reason in about 1973 or 1974.
The decimal system, specifically the use of decimal place value and numerals, is believed to have originated in ancient India around the 3rd century BCE. The concept was introduced by mathematicians like Aryabhata and Brahmagupta in their influential works. This system of numerals eventually spread to other parts of the world and is now widely used globally.
