Name

See also: Orders of magnitude (numbers)

Many languages have a specific word for this number: In English it is a myriad, in Ancient Greek μύριοι, in Aramaic ܪܒܘܬܐ, in Hebrew רבבה (revava), in Chinese 萬/万 (Mandarin wan, Cantonese maan6), in Japanese 万/萬 [man], in Korean 万/만/萬 [man], and in Thai หมื่น [meun]. It is often used to mean an indefinite very large number.¹

The Greek root was used in the earlier versions of the metric system in the form myria-.

The number can be written 10,000 (UK and USA), 10 000 (transition metric), or 10•000 (with the dot raised to the middle of the zeroes; metric).

In scientific notation, it is written as 10⁴.
It is also written as 1 E+4 (or as 1 E4)

The classical Greeks used letters of the Greek alphabet to represent Greek numerals: they used a capital letter mu (Μ) to represent 10000, whose name in Greek is myriad.
10⁴⁰⁰⁰⁰ = 10000¹⁰⁰⁰⁰ The value of a myriad to the power of itself, written (by the system of Apollonius of Perga) as a little M directly above a larger M.
