if a = b and b = c, then a = c

Is this some sort of new math?

A high school geometry teacher has been placed on paid leave and may be fired after using the example of shooting President Obama in a geometry lesson.

A student in the class described the lesson: “He was talking about angles and said, ‘If you’re in this building, you would need to take this angle to shoot the president.'” (Source.)

Think about the possibilities this opens up to finally, at long last, make word problems more interesting.

“Assume that little Johnny’s brain weighs 3 pounds. A pipe bomb is used to blow his head off, destroying 20% of brain mass. Then a chain saw is used to cut what remains exactly in half. How much brain matter remains?”

Yeah, much more interesting. Perhaps I should drop my plans to write a novel and go into mathematics textbooks instead. This might be the sign I’ve been looking for. This just might be my big break!
