Are these correct or not?

I can't hardly see you.
The children were real excited when they made the team, they jumped up and down noisily.

The first is wrong because it has two negatives -- can't and hardly. In English grammar, we do not use two negatives together.

It should be either: I can't see you. or I can hardly see you.

Do you see the two errors in the second sentence?
yes, maybe really and noisy?
Yes, really is one of the corrections. Noisily is o.k. However, there should be a semi-colon after team.
