Radix-5

Quinary or Radix-5 Number System
Quinary is a Radix-5 positional notation number system. Radix-5 or Base-5 means that each Quinary "digit"
represents a multiple of increasing powers of 5, from right to left, such as:
... 5^{3}, 5^{2}, 5^{1}, 5^{0}
The valid Quinary symbols are:
0, 1, 2, 3, 4
For example, the Quinary number 402 represents the number 102 in the Decimal system, like so:
(4 x 5^{2}) + (0 x 5^{1}) + (2 x 5^{0})History of the Quinary Number System
Many languages use Quinary, including the three Aboriginal Australian languages: Nunggubuyu, Gumatj,
and Kuurn Kopan Noot, as well as Saraveca, the extinct Arawakan language once spoken in Bolivia by the Sarave people.
Other languages use Biquinary, where 5 is the sub-base for a Decimal counting system, as for example, Wolof,
a language spoken in Senegal, The Gambia, and Mauritania, the native language of the ethnic group known as
the Wolof people, and also for example in Khmer or Cambodian, the language of the Khmer people, the official language of Cambodia.
Additionally, other languages use 5 as a sub-base for a base-20 counting system, as found in Nahuatl and the
Maya numerals. Nahuatl is a group of related dialects of the Nahuan or "Aztecan" language family native
to Central Mexico. The Maya numerals were invented and used by the Maya, an advanced pre-Columbian
civilization native to Central America.
Roman numerals employ a Biquinary number system, as do the Chinese and Japanese abaci.

Radix-10

Decimal or Radix-10 Number System
Decimal is a Radix-10 positional notation number system. Radix-10 or Base-10 means that each Decimal "digit"
represents a multiple of increasing powers of 10, from right to left, such as:
... 10^{3}, 10^{2}, 10^{1}, 10^{0}
The valid Decimal symbols are:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9
For example, the Decimal number 927 represents the following numerical expression:
(9 x 10^{2}) + (2 x 10^{1}) + (7 x 10^{0})History of the Decimal Number System
The modern Decimal number system, known as the Hindu-Arabic number system, originated in India around the 9th century CE.
The system spread to the western world during the Middle Ages (1000 to 1300 CE) as a result of trade.
Some scholars attribute the first documented use of a Decimal system to China in the 1st century BCE.
