Numbers in Tok Pisin occur with and without –*pela* suffixed to them:

** **1 *wan wanpela*

** **2 *tu tupela*

** **3 *tri tripela*

** **4 *foa fopela*

** **5 * faiv faipela*

** **6 *sikis sikispela*

** **7 *seven sevenpela*

** **8 *et etpela*

** **9 *nain nainpela*

** **10 *ten tenpela*

Those without –*pela* attached correspond to the names of the numbers in English and are used for mathematical operations like addition, subtraction, multiplication and division, and for counting money and telling the time, some of which will be presented in more detail later. Numbers beyond ten are not constructed as in English although one may occasionally hear the shorter ones with –*pela *attached to them, e.g.

** elevenpela ***eleven*

** eitinpela ***eighteen*

** twentipela** *twenty*

Sometimes an older method of counting beyond ten is resorted to in modern contexts to make sure that there is no ambiguity or doubt about what is said. For example, on aircraft where the noise level is high the hostess might say *The journey will take thirty-five minutes* and will use **tripela ten faiv minit** for *thirty-five* . The numbers in this older method of counting are based on ten (except for the hundreds) and are regularly derived. Consider, for example:

** **11 wanpela ten wan

** **12 wanpela ten tu

** **18 wanpela ten et

** **26 tupela ten sikis

** **54 faipela ten foa

** **80 etpela ten

** **100 wan handet

In the classroom **nating**, **not** or **siro** is used for *nought* or *zero* but outside it in everyday life the idea of nothing is expressed by **i no gat wanpela** (lit. *there is not one*). Approximations are given by **samting olsem**, e.g. **Em i gat samting olsem fotisikis kina** *He’s got about K46* (lit. *something like K46*).
