It's handy for working out which is the better deal in shops when they don't mark the price signs with equivalent price information. Say, for example, you want to buy some cans of juice. You can get a 6 pack with 50% extra free for £2.75 or you can get a 12 pack for £4.50. The price signs don't give you a figure like "10p per 100ml". Which is the better deal?
Except it isn't flawed. A safe assumption with life is that a lot of things were designed and figured out by people smarter than ourselves.
To buck the trend because we want to do our own thing on our own is only a good idea when we are confident that we are at least as intelligent or more intelligent than the person that initially made the theory.
That's not to say that you shouldn't question life or challenge other concepts, but when there's no logical reason why you would question that concept... what's the point.
lol man you're something else aren't you I admitted i have never encountered that kind of math assignment (or i don't remember it from highschool) when there's nothing beatween 2 and X, but you actually argued on 4 pages that you're right?
