That's not what counting cards means in blackjack. So when you start a game, you've got a count of 0. For every 2, 3, 4, 5, or 6 you get, you add +1 to that counter. For every 10, K, Q, Jack, or Ace (unless that counts as a 1) you get, you subtract -1 from that counter. If you get 7, 8, or 9, that's just 0. For example, if I draw a 7, and then a Queen, I'll be at -1 and I should stop there becausee it's more likely I will go over if I keep going. And always stop at 16, unless you're willing to risk your money.
There's a little more to that where you count the true average, but I'm not well-versed with that.
