10,000 (ten thousand) is the natural number following 9,999 and preceding 10,001.

Name

See also: Orders of magnitude (numbers)

Many languages have a specific word for this number: in Ancient Greek it is μύριοι (the etymological root of the word myriad in English), in Aramaic ܪܒܘܬܐ, in Hebrew רבבה [revava], in Chinese 萬/万 (Mandarin wàn, Cantonese maan6, Hokkien bān), in Japanese 万/萬 [man], in Khmer ម៉ឺន [meun], in Korean 만/萬 [man], in Russian тьма [t'ma], in Vietnamese vạn, in Sanskrit अयुत [ayuta], in Thai หมื่น [meun], in Malayalam പതിനായിരം [patinayiram], and in Malagasy alina. ^[1] In many of these languages, it often denotes a very large but indefinite number. ^[2]

The classical Greeks used letters of the Greek alphabet to represent Greek numerals: they used a capital letter mu (Μ) to represent ten thousand.^{[ citation needed ]} This Greek root was used in early versions of the metric system in the form of the decimal prefix myria-. ^[3]

Depending on the country, the number ten thousand is usually written as 10,000 (including in the UK and US), 10.000, or 10 000. ^[4]

In mathematics

In scientific notation it is written as 10⁴ or 1 E+4 (equivalently 1 E4) in E notation.

It is the square of 100 and the square root of 100,000,000.

The value of a myriad to the power of itself, 10000¹⁰⁰⁰⁰ = 10⁴⁰⁰⁰⁰.

It has a total of 25 divisors, whose geometric mean is a whole number, 100 (the number of primes below this value is 25). ^[5]

It has a reduced totient of 500, and a totient of 4,000, with a total of 16 integers having a totient value of 10,000. ^{[6] [7]}

There are a total of 1,229 prime numbers less than ten thousand, a count that is itself prime. ^{[5] [8]}

A myriagon is a polygon with ten thousand edges and a total of 25 dihedral symmetry groups when including the myriagon itself, alongside 25 cyclic groups as subgroups. ^[9]
