The numbers in Spanish
Tens
In Spanish, numbers from 0 to 15 has each a differentiated name.
After that, in numbers of two figures the name is a combination of the tens and the units, e.g. ‘cuarenta y dos’ (forty and two). More specifically, numbers until 30 are written in a word and after that the numbers containing tens and units will be written in three words, as we can see below.
18 → diez y ocho → diec i ocho (z+y or cy are not possible in Spanish) → dieciocho
25 → veinte y cinco →veint i cinco (we keep the “y/i” and “e” disappears) → veinticinco
67 → sesenta y siete
86 → ochenta y seis
Hundreds
The number 100 in Spanish is ‘cien’. However, each number above that and up to 200 will be written ciento + (two figures number).
100 cien
130 ciento treinta
155 ciento cincuenta y cinco
198 ciento noventa y ocho

Thousands, millions and billions
We do say, though, ‘un millón’ and ‘cuatro millones‘.
Attention:
A billion in English is ‘mil millones’ in Spanish (a thousand millions).
A trillion in English is a ‘billón’ in Spanish.
