What does it mean when you can't answer the question properly and said "4.5"?
- sukuriant 14y agoYou're either a math major or an engineer. We can't do simple math anymore. Please give it to us in the form of an integral. Also, there's the ambiguity of "inclusive or exclusive? And, which side?" [1,9], (1,9], [1,9) or (1,9)?
- kylebrown 14y agoThose ambiguities make no difference to the answer. Answering 4.5 just means you forgot that starting a count from 0 gives a different total than starting from 1.
- sukuriant 14y agoIf you're using the set of integers, then [1,9) is equivalent to [1,8]; and that would have a different answer from 5 for "what the center is"; so, it does affect the answer.
- kylebrown 14y ago[1,9) is not equivalent to [1,8]. The center of [1,9) is infinitesimally close to the center of [1,9]. Its exactly equal when you take the limit.
- sukuriant 14y ago... I was using that nomenclature for the short hand of "inclusive/exclusive". 1 to 9 exclusive is 1 to 8 in the integer set. Sorry for the lack of clarity. Perhaps now we can get to my original point?

- nostromo 14y ago4.5 is halfway between 0 and 9. Halfway between 1 and 9 is 1+(9-1)/2 = 5
- JoeAltmaier 14y agoNu-uh. By that math, halfway between 1 and 2 is.... 1?!
