Does buying more than 1 lotto ticket increase your odds of winning and if so by how much?

Of course, if you have 2 tickets with different numbers on them, you have one additional chance to win. Now, there are literally 10s of millions different combinations of numbers, so just buying 2 tickets isn't going to increase your chances very much. But, if you're buying lotto tickets, you're not really concerned about getting good odds now, are you? Good luck!
