Tibetan numbers greater than 20 use a numerical interfix to connect the first and second digit. These particles are unique for each set of 10: རྩ for 21-29, སོ for 31-39 , ཞེ for 41-49 , ང for 51-59 , རེ for 61-69 , དོན for 71-79, གྱ for 81-89, and གོ for 91-99. In written Tibetan, ཉེར may be used in place of རྩ. Since each particle corresponds to a unique value of ten, the interfix can be used in place of using the full name of the second digit (e.g. སོ་གཉིས for 32 instead of སུམ་བཅུ་སོ་གཉིས). Interfixes are not used for numbers that end in 0. Additionally, one may emphasize that a number ends in zero by appending ཐམ་པ to the end (e.g. བཞི་བཅུ་ཐམ་པ, བརྒྱ་ཐམ་པ). Numbers in the third digit are separated from second or first digit using the particle དང when written and ར when spoken (e.g ཉིས་བརྒྱ་དང་བརྒྱད་ཅུ་གྱ་གཉིས or ཉིས་བརྒྱ་ར་བརྒྱད་ཅུ་གྱ་གཉིས for 282). If the third digit is zero in a four digit or larger number, this is represented with the phrase བརྒྱ་མེད, literally "without hundred" (e.g. ཉིས་སྟོང་བརྒྱ་མེད་དང་ཉི་ཤུ་ཉེར་ལྔ).
