Learn Farsi: سه ماشین بیرون است. - There are three cars outside.

In Farsi, nouns that come right after a number always stay in their singular form. So, instead of saying "three cars", you literally say "three car" (سه ماشین).

Why does the sentence end with است (is) instead of a plural verb for "are"?

In Farsi, when the subject is an inanimate object (things that are not alive, like cars or chairs), the verb is usually singular. Even though there are three cars, the verb است (is) remains singular.

How does this sentence mean "there are" if it only uses the word for "is" (است)?

Farsi does not use a separate phrase like "there is" or "there are" to state that something exists in a location. You simply name the subject and where it is. Literally, this sentence translates to "Three car outside is."

Why is the word for outside (بیرون) placed in the middle of the sentence?

Farsi places the verb at the very end of the sentence. Location words like بیرون usually go right before that verb. So the order here is Subject (سه ماشین) + Location (بیرون) + Verb (است).
