Number names in English and Spanish

In English and Spanish, there are two types of numbers, and different ways to call each of them. Here I include the numbers and a few bits of explanations.


In Spanish

Cardinal numbers

These numbers are used everyday. They indicate either quantity or magnitude.

In English...

+ from zero to twenty, they all have their own name
+ from there onwards, the last two figures of a number name will have a hyphen
+ over a million, every three additional zeroes (or multiplication by a thousand) will have an new name

While in Spanish...

+ from zero to thirty, they all have their own name
+ from there onwards, the last two figures of a number name will be named using the ten and the unit
+ over a million, every six additional zeroes (or multiplication by a million) will have an new name

Ordinal numbers

Ordinal numbers express position, so they both are integers and don't have a zero. In Spanish, you abbreviate the position writing the number plus a degree symbol (º). In English, you abbreviate the position writing the number plus the last two letters of its name (st, nd, rd, or th). You should also know that in Spanish the names of the positions may change the last 'o' to 'a' to match the noun gender.
