How Oral Math Can Go Wrong

QOC (reading from the math page): There are six teaspoons in a set. How many are in two sets?

Deux: 120.

QOC: I mean in the real world, not in your world (in his world, all amounts are automatically ten times greater).

Deux: I did answer in the real world. Oh--did you mean sixteen?

QOC: No, not sixteen. Six. Six teaspoons.

Deux: Right, two sets of sixty spoons is 120.

QOC: Oh. Teaspoons. As in these (holding up teaspoon). Six of these in a set. How many in two sets?

Deux. Oh. Twelve.
