I sigh and release my inner preacher, "So because the problem is 2+3, you count to 2 first. Now that you've used the 2, you count up three more numbers. It helps if you do it on your hands as well, on your left put up two fingers and your right, three. Now transfer one digit from your right to your left. You should have one on your right hand and four on your left. Now just so that one more time and that's your answer." I turn around to look at her, "So, what did you get for your answer?"
