As people have said, it has various possible translations, but I'd say that the most basic meanings are "so; so much; thus; thusly."

Also, note that it can serve as a counterpart (and answer) to как, which can be an interrogative meaning "how?" or a conjunction meaning "as; like". Sometimes так and как are paired in a sentence, and in such contexts, так signifies "the same way":

Мария ответила на вопрос так же, как Борис. ("Maria answered the question the same way that Boris did.")
