Can also or also can???

.
It may go in either position in most situations, I think, but the normal position is after the auxiliary: may also, can also, should also, etc.
.

Do they mean slightly different things?
For example, "I can also give you ten dollars." means "Besides giving you ***, I can also give you ten dollars."
"I also can give you ten dollars." means "I know he/she can give you ten dollars. I can give you ten dollars too."

I am confused. Please help!

.
No, there is no intrinsic difference in meaning. The differences you suggest will have to appear in the context.

Thank you very much, Mister Macawber.

I agree with your explanation since it is stated clearly even in the dictionary and various grammar books that the word 'also' (which means 'in addition' - a logical connector) is placed after the auxillary verbs (there are 10 AV). It sounds more formal when used unlike 'also can' or 'also could' which sounded more informal and colloquial (ordinary conversation, informal).

If I understand your post correctly, Anon, you think there is a difference in the level of formality. However, I don't think formal vs informal is really a factor here. I'd say it's primarily just a question of which word order is more commonly used.

There was another thread about this earlier today

"I can also give you ten dollars." - You (I) can give an additional ten dollars to what you have already given.
"I also can give you ten dollars." - You (I) can give 10 more dollars on top of what someone else has already given.
