Number Woes!

Sammy came home from school with a red ear.
Father: What happened?
Sammy: This is because of Mathematics.
Father: Why? You`re good in Mathematics.
Sammy: The teacher asked me, `What is three times two?`
Father: What did you say?
Sammy: I said six!
Father: Good. So why the red ear?
Sammy: The teacher asked me what is two times three?
Father: That`s fucking same!
Sammy: That`s what I said.
