Math

We were driving home from the grocery store.  The little woman was quizzing the little man on math skills.  Always a good practice for her.  So she must have given him a problem beyond his ability.  So he asks me what is 50-40.  I tell him 10.  He tells me he isn't used to big numbers yet.  He can do little numbers.  And he gave me an example. 10+5-1.  And then he told me the answer was 14.  Yup right on.  End of kindergarten and he is already starting to understand order of operations. I am always amazed when I realize just what they know.....already. Oh and he can add by tens, just not subtracting yet.  Bet he figures it out really quick.
