Употребление артикля перед числительными

a) Как правило, когда определение выражено количественным числительным, существительное употребляется без артикля: Two men entered the room.

Если же перед порядковым числительным употребляется артикль, то он приобретает смысловое значение: the two - эти два или оба - и часто обозначает полное количество объектов:

b) Перед порядковым числительным обычно употребляется определенный артикль. Однако, когда порядковое числительное имеет значение другой, еще один или неизвестно общее число предметов, действий и пр. употребляется неопределенный артикль:

A third man (еще один) entered the room.

c) Артикль не употребляется перед существительным, если за ним следует его номер:

I'm waiting for tram 55.
