You have to count the number of carbon environments and multiply them.

Hi, I want to know the answer of the silver level, because I try with decimals, without it; But never works, so I want to correct answer, please.

You need to give the answer to 3 significant figures. We're quite a long way into this months challenge so I suppose it would be okay to give you the answer.
