The cards are dealt face up and the dealer announces the cards, both yours and theirs, as they are revealed. Not all dealers are good about remembering to do this, but it is something they have all been trained to do. If you have a crummy dealer, move to another table.
The dealer is under no obligation to tell you your total unless you've busted though some will read the hand rather than the specific cards, ie. They will say "16" rather than "9 and 7" or "7 or 17" rather than "ace and 6". This can be good and bad. We have had dealers who read a pair of 8's as "16" and failed to mention it was a very desirable pair against a low dealer card. Others at the table spoke up and urged us to split rather than stand.
