comment Splitting a sandwich and not feeling deceived
@user21820 Ah thanks, your last comment made sense, i understand the problem now. Learning something new every day :) As for the wikipedia argument: Over half the questions and answers on stackexchange could probably be referred to wikipedia, so that point is mood.

Also i did not read wikipedia but nobody else here mentioned that specific way so i tought it was fair to add it.

comment Splitting a sandwich and not feeling deceived
The second solution is obvious less work and therefore less fair; however if you add the assumption that when person 1 cut out 5/6 cake, person 2 and 3 might argue he meant to take only 1/6 part himself. Even when person 1 and 3 work together, this method still makes it hard to give person 2 less than 1/4th of the cake. If person 2 expect treason, person 1 can give him 1/2 cake and he can cut it into 1/4th parts. It works of course better when all players try to maximize there share.

comment How would you explain to a 9th grader the negative exponent rule?
With my programming background I could swear the unarry (-) binds stronger than anything else, but for clarity I've updated the answer. Also, who is this woman you are referring to?

comment Strange results on removing lim in wolframalph
I did start with h, but i already lost it along the road. If you really want to know, this was my starting point: [lim ( ((2*(x+h)-1)/(3*(x+h) -2) - (2x-1)/(3x-2) ) /h) as h->0]

comment Strange results on removing lim in wolframalph
I'm pretty sure I wrote ${h \to 0}$. The question is mostly about why the second wolfram link is not considered equal by wolfram. The first one say "Result: True", the second does not. When i remove the limit from both, they are true.

Actually the my left hand side was (3x+3h-2)(3x-2), since h lim 0, I removed the h. Can you explain why the second Wolfram link is not true?
