Adventures in Pedagogy: Order of Operations

Nevan (8) goes to the counter to grab a pack of gum from a box that contains four different flavors.  He says, "Hey Dad, look.  There's four different kinds of gum in here."

Oh, yeah?  How many of each kind are there?


Then how many packs of gum are in the box?


Really?  How do you get ten?

"Yeah, we've eaten two."
