Hi everyone,

I need your help with cardinal numbers. After following this lesson http://bit.ly/ds8uxy, I have some questions.

This summary basically explains it all:
Quantity ends in 1 - As per position in the sentence.
Quantity ends in 2,3,4 - Genitive Singular.
Quantity ends in 5,6,7,8,9,0,-надцать - Genitive Plural
General Quantity - Genitive Case (Singular or Plural depending on context.)
Quantity not specified - Use the case that is appropriate to the sentence position.

Does this apply to all of the cases or just the nominative case? For example, If I wanted to say "I have five black cars" would it be "Я хочу пять чернокожих машин" (where the adjective and noun are genitive plurals, but the number is nominative) or would it be "Я хочу пять чернокожие машины" (where the adjective and noun are inanimate-accusative plurals, and the number is accusative)?

Also, does the adjective always agree with the noun?

I'm finding this very confusing

Any help would be greatly appreciated!

Mark
