so I have a group of players that I have been playing with for a while now. A couple of them have never played before so I understand that they will likely not remember a ton of the rules. I've dmed for them from level 1 all the way to level 12 at this point, and a couple of the players ask me every time what they add to an attack roll. I was wondering while not being a jerk about it is there any tips to help them with basic stuff like that?
