The Thai counting system is quite similar to the western counting system. The general rule is that the leftmost digit is mentioned first, for example: for two digit numbers, the second digit unit is 'sip2'. For 10, it is just plain "sip2". For 12, it is the digit 10 followed by 2, hence "sip2 s@@ng5". For 30, it is 3 times of the digit unit 10, hence "three ten" or "saam5 sip2". For 34, it is 3 times 10 followed by 4, hence "saam3 sip2 sii4".

There are a few exceptions, of course. 20 is "yii3 sip2" (not s@@ng5 sip2 as you would have guessed). Historically, "yii3" is an archaic thai word meaning 'two'.
And 1 in the first digit (such as in 11, 21, etc..) is pronounced "?et2", not "nUng2". However, since "?et2" sounds very similar and can be confused with 7 (cet2), it is common practice for the military to use "nUng2" in all positions for clarity.
