Shady Math

In trying to teach in everyday experiences, Daddy tried to teach Nat a little math last night. He had some vitamin bottles on the kitchen table. Two were in one group and two in another group.
Daddy asks, "What's two plus two?"
Nat: "I don't know."
Dad: "OK, well let's find out." He moves the two groups near each other "OK, let's count them."
Together: "one, two, ... three, four"
Dad: "OK, so what is two plus two?"
Nat: "asthma"
