Torture - Otherwise Known as Homework

Here we are, trying to get through another night of homework. 

Part of tonight's assignments: a subtraction worksheet. We've been arguing over the first problem for the last ten minutes. 

"Al, what's 15 - 11?"

"Six."

"No, Buddy. MINUS."

"Six. Five plus one is SIX!"

"Well, yes, but this is subtraction, dude."

"But it is six."

Ugh. We've got eight more problems to argue over before we move on to spelling words.
