In Russian, using prepositions with numbers can change based on the situation.

This is especially important for the noun that follows the number.

If you want to speak Russian well, it's key to know how to combine these correctly.

Here are some important points about using prepositions with numbers:

Common Prepositions with Numbers:

1. в (in):

   • How to Use It: This preposition shows where something is or where it's going.
   • Case You Need: Use the accusative case when you’re talking about direction. Use the prepositional case when you’re talking about a location.
   • Examples:
     • в три часа (at three o'clock) – This uses the prepositional case.
     • в три месяца (in three months) – This uses the accusative case.

2. на (on, at):

   • How to Use It: This shows a surface or an event.
   • Case You Need: Always use the accusative case with this preposition.
   • Examples:
     • на один день (for one day) – This is the accusative case.
     • на два года (for two years) – This is also the accusative case.

3. с (with):

   • How to Use It: This shows being together with someone or including someone.
   • Case You Need: Use the genitive case for numbers 2 to 4. Use the accusative case for 1 and numbers higher than 4.
   • Examples:
     • с одной подругой (with one friend) – This is the accusative case.
     • с двумя братьями (with two brothers) – This is the genitive case.

Special Notes:

• For the numbers 2, 3, and 4, when you're using с, make sure to use the genitive singular case for feminine nouns.
• The form of the number can change based on whether the noun is masculine, feminine, or neuter.
