Numbers are among one of the first things we learn when learning a new language.

 There are two types of numbers; cardinal and ordinal.

A numeral is a figure, a symbol, a word (or their combinations) representing a number. It denotes the number of objects, their number, and also the order when counting objects.There are cardinal and ordinal numbers.

The cardinal series are derived from cardinal numbers, such as English one, two, three.
The multiple series are based on adverbial numbers like English once, twice, thrice.
The distributives originally meant one each, two each or one by one, two by two, etc., though that meaning is now frequently lost.
The ordinal series is based on ordinal numbers such as English first, second, third. For numbers higher than 2, the ordinal forms are also used for fractions; only the fraction ½ has special forms.
