Decimal system is a number system based on 10.

A polygon with 10 sides is called a decagon.

There are regular decahedrons on the surfaces of truncated dodecahedron and truncated icosahedron.

The faces of all Zhan Sen polyhedrons are composed of regular polygons of 3, 4, 5, 6, 8 or 10.

It can be written as the minimum number of the sum of two prime numbers (3+7, 5+5) in two ways.

The common logarithm is a logarithmic function with the base of 10, and its inverse function is an exponential function with the base of 10.

Because 10 is easy to calculate in decimal, many units with the same length (meter) and weight (gram) are decimal. Most currencies in the world adopt the decimal system (Britain and some other Commonwealth countries later evolved the decimal system). For example, 1 yuan equals 10 minute, and 1 minute equals 10 minute.

10 can be decomposed into the sum of squares of two different odd numbers (10= 1? +3? ) and is the smallest positive integer satisfying this property.

Logarithm with the base of 10 is often used in astronomy, and it is recorded as lg. In mathematics, it is expressed as logarithm.

Scientific counting method: in mathematical terms, a number in the form of a× 10 to the power of n is expressed as (a×/kloc-0 to the power of n), where 1≤|a| 10, and n is an integer. This counting method is called scientific counting method.
