I thought a double negative would make the point more clear than a double positive, you are lucky I did not venture into the irrational numbers domain, nor into the complex numbers domain. I could have made life really difficult and ventured into quaternions as well, but I am not in a sufficiently bad mood, even though, it was a lousy day in the markets (red, yes a red day on balance, ouch).
