thirteen
(13, XIII, 十三, trece, tredici, 열세, तेरह, ثلاثة عشر, тринадцать, treze, dreizehn, baker's dozen, 11012, שלוש עשרה)
Take any number (or anything that thinks it's a number) and multiply by thirteen.
From Wikipedia:
13 (thirteen /θɜrˈtiːn/) is the natural number following 12 and preceding 14.
In spoken English, the numbers 13 and 30 are often confused. When carefully enunciated, they differ in which syllable is stressed: 13 /θərˈtiːn/ vs. 30 /ˈθɜrti/. However, in dates such as 1300 ("thirteen hundred") or when contrasting numbers in the teens, such as 13, 14, 15, the stress shifts to the first syllable: 13 /ˈθɜrtiːn/.
Thirteen is represented in numerous ways, depending on the desired counting system. Outside of the common base-10 system, here are a few examples of other ways to understand the number 13:
Ndom (Base-6): 13 = (6 x 2) + 1
(Base-12): 13 = 10 + 1 where 10 in Base-12 is equal to 12 in Base-10
Oksapmin (Base-27) : 13 = right ear + right thumb
Alamblak (Built from 1,2,5, and 20) : 13 = (5 x 2) + 2 + 1 = tir hosfi hosfirpat
