"В комнате два окна."

Translation: There are two windows in the room.

[cmansenior05]

is окна one of those irregular plurals? like город - города?

[Berniebud]

No. numbers 2, 3, and 4 require the genitive singular.

The genitive singular ending for neuter nouns is "-а".

Additionally, the nominative plural ending for neuter nouns is also "-а", so "Окна" is a very regular plural as well.

[hud214]

It wouldn't accept "In a room there are two windows."

[MrHarryRay]

Since кровать is at the beginning of the sentence it's more likely to be "the room".

Also, this course prefers English sentences of the form "There is/are X located at Y" to the form "Located at Y is/are X". Not sure why but I suspect the latter are not quite grammatical?

On which syllable is the stress placed in the word окна? Thanks!

[Venya_Dixon]

Probably a bit late, but it is on the letter а. One way to tell is that when you hear окна you can tell the o is pronounced as a. This is because unstressed o is pronounced as a.

[Roberto740984]

In the room, two windows

[Phil_Stracchino]

I would have translated this as "The room has two windows." Is this also reasonable?

[Dusttuft]

I wrote the number 2 and it declined it, i think we should be able to write the number instead of spelling it

[JewishGum]

That idea misses the whole purpose of this course. Learning a language means to obtain the ability to read, spell, pronounce and understand both words and numbers. Even the exercise is called "Time&Numbers"
