Here is a way to cut a perfectly circular pizza into sector-shaped slices for N people some of whom demand small slices, some large, and the rest will accept any size: First choose any irrational number s . Cut the pizza from its center east to its edge; then turn the pizza through an angle s*pi clockwise and cut it again from its center east to its edge; repeat this turn-and-cut until the pizza has been cut into N sectors. Prove that they have just two or three different sizes. \n\nMuch harder problem: how do you choose s?

OMG a math riddle I cant seem to answer!!!! :-)  Awesome. I cant sleep because now i want to knwo the anwer. And so i continue to try and solve it.\n\nBest i can come up with is 113  or 240 or 50-something..\nAlso maybe another number in the 100-n-teens\n\nI did find a 1-3-4 pattern aasuming the next number in 1-3-4-1 was a 3 but was unsure of how to continue it. (its1230 in the moring here)\n\nAnd again another possible patter 1-3-4-8 next number would be 16.\n\nI know some may not even know how I came up with these, but I love math and I love a challenge. I have been trying to find any possible correlation in the numbers that I can. \n\nHope someone figures it out. I know I cant wait to see the answer.

Ask Dr. Math is my favorite.  You can also try Mathworld, though I usually find that I leave it more confused than when I entered.

Try http://www.edhelper.com/number_puzzle.htm.  I don't know what your subject matter is, so this is the best I can do.  Toward the bottom of the page are puzzles on algebra, polynomials, systems of linear equations and inequalities.

Alrighty! This one has been floating around for a very long time and this is the Third instance of the same riddle i've seen. I will cover it accordingly and supply the Answer so bare with me\n\nThe Riddle!\nCorrect Version....\nIn all instances of this riddle you notice that the title states "Find the Error" , Or "Find The Error For Me", or "Can you find The Error".  The Title is the KEY.. Notice how it just ask you to "Find The Error" it does NOT however state "What" kind of Error.. This is pretty much the meat and potatoes of the Trick Question..\n\nIncorrect Versions...\nNow there are some instances that actualy go as far as to say " Find the Error in The Alphabet". These titles are incorrect and defeat the purpose of the Riddle.. Fact of the matter is There IS NO ERROR in the Alphabet, or should NOT be.. But since the title was posted wrong, this confuses the Readers to the REAL problem and answer..\nSome have even "Intentionaly" distorted the alphabet by adding a "0" into the mix instead of the "O". Now this is tricky, yes, but once again. Incorrect, and defeats the purpose of "Misdirection"\n\nAlso another mistake people make is they "Repost" The riddle by hand INSTEAD of just copyiing and pasting it  the way they should. So it gets distorted as it moves on. This case is NO exception. The mistake made in this instance is with the sentence \n"find the error. it's impossible" <- this is the incorrect version\nit should be\n"find the error. its impossible"<-This is the Correct version \nNotice how in the "Correct Version" of the Riddle, I Intentionaly Neglected the Apostrophe between the "t" and "s" :) That is because THIS is the Error the reader is supposed to find. It's a grammatical Error NOT an Alphabetical.\n\nThe Answer!\nThe Error Is Not In The Alphabet\nNow since we know what the Real Version Is, let's cover the Answer.  As said.. the Title is a "Trick" Question.. when stated correctly, the Reader "Assumes" that the error WANTED is in the Alphabet , even though it was not Directly Stated, so you search the entire Alphabet for Anything that could be possibly seen as "Wrong" but this is intentional  Miss direction..\n\nThe Error SHOULD be in the actual question ABOVE the alphabet list .\n\n"find the error. its impossible" \n\nNotice how in "Its impossible", there is no apostrophe between the "t" and "s".. At least when this riddle is posted "Correctly", there should be "NO Apostrophe"..\nThe absences of the apostrophe is the "Error" of which the reader is supposed to find..\nConclusion..\nWhen you repost this riddle be sure you just have the title read "Find The Error" and try not to convert it in any way.\nAlso never try to retype the riddle by hand unless you KNOW exactly how it's stated. People already tend to make grammatical errors when typing as is and others tend to make NO mistakes whatsoever , either way , this this distorts the Riddle...
