10 (ten) is the even natural number following 9 and preceding 11. Ten is the base of the decimal numeral system, the most common system of denoting numbers in both spoken and written language.
Linguistics
[edit]- A collection of ten items (most often ten years) is called a decade.
- The ordinal adjective is decimal; the distributive adjective is denary.
- Increasing a quantity by one order of magnitude is most widely understood to mean multiplying the quantity by ten.
- To reduce something by one tenth is to decimate. (In ancient Rome, the killing of one in ten soldiers in a cohort was the punishment for cowardice or mutiny; or, one-tenth of the able-bodied men in a village as a form of retribution, thus causing a labor shortage and threat of starvation in agrarian societies.)
Mathematics
[edit]Ten is the smallest noncototient number.[1] There are exactly 10 small Pisot numbers that do not exceed the golden ratio.[2]
Decagon

Music
