1. The so-called "quantifier" in German is actually a noun. Of course, it can be divided into masculine, feminine and feminine, such as:
A bottle, a glass, a bottle.
2. When a masculine or neuter noun is used as a quantifier, even if there is a plural form (such as glases, the plural is Glaeser), the preceding number is greater than 1, and there will be no plural change.
3. The feminine nouns are used as quantifiers. If the previous number is greater than 1, the plural form is applied.
