If you've studied other languages, some of these numbers may seem familiar. If not, du, tri and dek should at least sound familiar. Consider the English words duet, dual, tripod, tricycle, and decade, for instance.

Although the title of this post is "Let's Count to Ten", you can actually count to ninety-nine (99) with just these ten numbers. It's just a matter of addition or multiplication.

11 - dekunu
12 - dekdu
13 - dektri
14 - dekkvar
15 - dekkvin
16 - dekses
17 - deksep
18 - dekok
19 - deknaŭ
20 - dudek
21 - dudekunu
22- dudekdu
30 - tridek
99 - naŭdeknaŭ

See the pattern? It doesn't get much simpler than this.
