Decimal with some vigesimal influences in specific multiples
10

Interlingua uses a decimal base system, where units from 1 to 9 are unique words: un, duo, tres, quatro, cinque, sex, septe, octo, nove. Tens are formed by suffixing the multiplier digit with -anta, with exceptions for ten and twenty: deci [10], vinti [20], tresanta [30], quaranta [40], cinquanta [50], sexanta [60], septanta [70], octanta [80], novanta [90]. Compound numbers are formed by hyphenation, such as deci-duo [12], septanta-nove [79], showing a pattern of combining tens and units. Hundreds are formed by placing the multiplier before 'cento' (e.g., duo centos [200], tres centos [300]), and thousands similarly with 'mille' (e.g., tres milles [3,000]). Larger numbers follow the long scale, with 'million' (106), 'milliardo' (109), 'billion' (1012), etc., each built by multiplying the previous scale by one million.

Counting rules

1

Units

Numbers from 1 to 9 are unique words: un [1], duo [2], tres [3], quatro [4], cinque [5], sex [6], septe [7], octo [8], nove [9]. For example, 6 is sex, 9 is nove.

2

Tens

Tens are formed by suffixing the digit with -anta, replacing the ending e or o with a, except for 10 and 20. For example, 30 is tresanta, 40 is quaranta, 50 is cinquanta, 70 is septanta, 80 is octanta, 90 is novanta. 20 is vinti, which is an exception.

3

Compound numbers

Numbers between 11 and 99 are formed by hyphenating the ten and unit. For example, 12 is dece-duo, 17 is dece-septe, 42 is quaranta-duo, 78 is septanta-septe, 79 is septanta-nove.

4

Hundreds

Hundreds are formed by placing the multiplier before 'cento' with a space. For example, 100 is cento, 200 is duo centos, 300 is tres centos, 400 is quatro centos, 500 is cinque centos.

5

Thousands

Thousands are formed similarly with 'mille'. For example, 1,000 is mille, 2,000 is duo milles, 3,000 is tres milles, 4,000 is quatro milles, 5,000 is cinque milles.

6

Large numbers

Numbers larger than one million are formed using the long scale: un million (106), un milliardo (109), un billion (1012), each multiplied by the previous scale, with suffixes -ion and -iardo. For example, 1,000,000 is un million, 1,000,000,000 is un milliardo.
