Mr NuMetal:

saying that pythagorus' theorom won't help you put food on the plate is quite simply dumb, surveying, architecture and engineering all use this basic formula of a2+b2=c2 quite regulaly

oh and last time I checked all 3 of those jobs weren't exactly underpaid either.

maybe you should listen in school, you don't know what you might learn or more importantly when you might need to know it.
