Draft:Upper Decimal Number System

Upper Decimal Number System (Tr. Üst Onluk Sayı Sistemi) is a number system that has not been seen in any language in the world except Old Turkic. The basis of this system is the military system used by the Old Turkic People. The system says that the numbers after the first ten belong to the second ten, and the numbers after the second ten belong to the third ten, and it states that the number 11 is not connected to the first ten -10-, but instead to the second ten -20-.

For example, in today's Turkish, the number 17 (on yedi) is said as 10+7, and this indicates that the number 17 belongs to 10, that is, the first ten. However, in Old Turkic, the number 17 belonged to 20, that is, the second ten, and was pronounced as yedi yirmi (seven twenty), not on yedi (ten seven).[1]

Below are some examples of this:

Number Modern Turkish form If the Upper Decimal Number System was used today
11 on bir (ten one) bir yirmi (one twenty)
15 on beş (ten five) beş yirmi (five twenty)
25 yirmi beş (twenty five) beş otuz (five thirty)
32 otuz iki (thirty two) iki kırk (two fourty)
48 kırk sekiz (fourty eigth) sekiz elli (eight fifty)
53 elli üç (fifty three) üç altmış (three sixty)
69 altmış dokuz (sixty nine) dokuz yetmiş (nine seventy)
