It is common in asian languages to use the system 1+10+1 or 2+10+2 (for example: Thai: sam-sip-sam = 33, Japanese: ni-jyu-ni = 22, Chinese: chee-shi-chee=77 (I can't type tones, for Thai and Chinese, sorry)). The English system is similar in structure but not completely logical and probably has an origin. It is just the way the languages have evolved. So the numbers 1 to 12 have unique, non-systemic words. It is common to find discrepencies in other European languages. In French the number 77 is structured 60+10+7 not 7+10+7. There are other discrepencies in English too although not so obscure: Twenty instead of two-ty and fifty instead of five-ty. The big numbers are also counted differently. In English: Hundred (100), Thousand (1000), Ten-thousand (10,000), Hundred-thousand (100,000). In asian languages there is usually a single word for 10,000 not ten-thousand.
