Like Chinese language, Chinese numbers are written quite differently from the Arabic numeral system, which first came into China between the 13-14 century.
It wasn't popularly used until the 20th century, but the Chinese numeral system, which is also a base-10 system, has prevailed all the time.
Chinese people use characters for numbers. Like shown above, there is a character for each number from zero to ten. Zero can be writen as a circle in some informal situations, and 2 is writen and spoken as "Liang" very often when not used in two-digit numbers.
The characters demostrated on this page are in Simplified Chinese, which is used in mainland China.
From 0 to 10, count the numbers as they are.
As you can see, there are few strokes in some of the Chinese numbers, especially for the numbers 1,2, and 3. It's easy for a person to change it. Just add a horizotal stroke and the number can increase dramaticaly.
To prevent this from happening, Chinese people use a set of more complicated numerical characters on bank statements, checks and other important documents. These characters are shown as below:
There are two common shorthand characters for 20 and 30. Newspapers and some older writings use them very often, especially when it comes to date.
