What is the object of your "multiplication test"? I am an engineer and use math every day. Are you suggesting that if I don't answer your question correctly, then my abilities as an engineer are diminished? What does multiplying -2 x -2 have to do with the theory of evolution?
I assume you apply this same test to your dentist? Because surely he's not qualified to do a root canal if he can't explain why mutliplying two negative numbers yields a positive number.
