    Now that’s just impressively embarrassing.

    • lol says:

      SECOND!!!

      • BlaM says:

        LOL @ the circular logic in the response. He used (Study = Pass) in his assumptions and went on to “prove” (Study = Pass). Logical Fallacy Fail.

        The actual reason that it doesn’t work is he’s trying to use mathematical algebra when he should be using logical algebra. Let’s restate it:

        ~Study = Fail
        Study = ~Fail

        If you OR them together, you get a tautology, which says “If you study or don’t study you’ll either fail or don’t fail”, which doesn’t tell you anything, since it’s a tautology. You can reverse them (which is valid, since it’s an equivalence) and OR them together, which says “If you don’t study or don’t fail, you either study or fail”, but eliminating the logical impossibilities, since you can’t have both a proposition and it’s opposite be true, you just end up right back where you started with the original statements.

        You can AND them together as is, you get a logical impossibility on both ends for the reason stated above. If you reverse them before you do, which again is valid since they’re equivalences, you get “If you don’t study, you fail and if you study, you don’t fail” which is the exact opposite of his conclusion and states the obvious.

        Looks like everyone in that set of responses fails for not understanding basic first order logic.

    That’s a major Geek burn. X)

    -awards the last post five internets-

  3. Schouky says:

    Ah!
    This is why I love maths!
    You can’t cheat on maths!

  4. Arty says:

    Yawn! lol Boffin humour!

  5. Jake says:

    Daaaaamnit. I believe, sir, you just got owned.

  6. xinorl says:

    Geeks rock lol

  7. frogger says:

    now if no study is the opposite of study, wouldnt no study + study=(-1+1)study, therefore being 0=0? and prove nothing?

  8. Joce says:

    The problem with that is (No + 1) = 0 so you divide by zero and that cause the formula to go nuts :P

  9. Mr.Smiles says:

    i do know of some kids that use the word “studying” as code for getting high and etc.

  10. cowboy says:

    they just facepalmed each other… those funny geeks *sigh*!

  11. mmmmm says:

    I don’t get why the second guy thinks he can start out with the assumption that [study=pass]. He started out directly with a contradiction of the initial solution.

  12. noclue52 says:

    that was amazing!!! Q.E.MUTHAF**KING.D!!!!!!!!!!!

  13. Python says:

    ^^^how to spot virgins^^^^ lolol

  14. Mr.Smiles says:

    and that could be a rap ” Q to tha E and a MOTHAF**KIN D. Droppin straight knowledge all up on yo street. schoolin yall homes, with math matic expression, and then curb stomp till yo face leaves an impression” WORD!

  15. Lottery says:

    Do you reckon that last guys owns all the star trek series too? I am betting yes!

  16. koopa says:

    Ah, I love Math.

    Math geeks rule!

  17. Steve says:

    The end of the last comment really seals the deal. It was just a wild nerd battle until the last word, then I nearly fell out of the chair laughing! Well done.

    • Ometiklon says:

      Wild nerds are far more dangerous than tame ones. I once saw a couple of wild nerds fight over a graphing calculator – that was some intense s**t. You won’t see anything like that in the nerd exhibit at the zoo.

  18. You don't want to know the name, do you? says:

    Hahaha, Ja just got owned!!

  19. whata f**k dude!
    don’t understand :(
    it’s just wierd to talk about it =S

  20. wax on,wax off says:

    “Q.E.MUTHAFUKIN-D” lol, gotta love it. pwnage.

  21. plasket says:

    But if pass = no fail, then transitively no pass = fail. Using the same calculations, pass = fail, QED.

  22. captain maths says:

    actually, the assumption is that No Study and Study obey the associative property, not commutative. and ACTUALLY actually, the assumption is the the word joining operation is associative, not the words themselves. just sayin people, basic group theory.

    • Icarus says:

      … You’re saying English language isn’t a group with the word joining operation? Blasphemy!

      Really, he used all three assumptions( commutative, associative, and word order). You’ll notice that while factoring he switched the order of “fail” and “no fail” to have “(No +1)Fail” at the end.

      And finally, this:

      Maths: it IS serious business :)

  23. some other says:

    Study = Pass = Fail…

    so basically means that studying doesnt matter (I assume that it’s the ass sucking that does the passing then…)
    go on then and get a beer @ the pub..

  24. quedds says:

    You killed it plasket. This was hilarious tho.

  25. Steve D. says:

    How about (No Study + Cheat) = Pass?

  26. Luna says:

    I think Ja— must be this guy’s less successful cousin;

    http://www-users.cs.york.ac.uk/susan/joke/exoendo.htm

  27. noah says:

    What if (No + 1) = 0? Then you can’t cancel.

    Based on these results, I’m pretty sure No = -1, i.e. No Study = -Study, etc.

  28. Sesoron says:

    I think the primary problem here is that he intertwined the two material implications so that S*~S>~F*F, which no law of formal logic gives us based on (S>~F)*(~S>F).

  29. Dave says:

    I don’t see how he got from [(No study= fail) + (Study = No fail)] to the first line.

  30. Alec says:

    In this case, No = -1 in order as a contradictory statement so the final step of the proof contains a zero-divisor. Therefore, you haven’t said anything, just proved that 2 unequal things are equal when u don’t actually care what they are equal to. Good deduction, bad induction.

  31. The Toxic Mite says:

    Lol, the guy who posted the second comment is such an arrogant bastard

    • Anon says:

      the second comment? same as the OP

    • Miss Fit says:

      Nah, that’s the OP, who’s referring to the first comment that said “You fail”. Hence his answer, which his so-called calculation was all about; “because I studied [I failed]“.

  32. Wow says:

    How could (x=y)+(a=b) give any reasonable outcome? And how can you then change it to (x+a)=(y+b)? And wouldn’t (No Study + Study) equal to ((-1)*Study + (1)*Study) resulting in (-1+1)Study equaling 0*Study? How could you then get rid of the brackets besides dividing by zero (BAD IDEA!!!)?

  33. Terell.W says:

    OWNED!

  34. Ally says:

    yeah i never study for tests and i get well in the 90′s and when i do study i get a failing grade (to me failing is 85 below)

  35. Brad says:

    It’s quite obvious that No = -1 in this sense.

  36. Damenuendo says:

    The problem with the proof is that he eliminates the equivocating factor, being the (No + 1). Since, in this context, no is representing the opposite, No is equivalent to negative one, therefore within the brackets equals zero, which makes the two sides equal. Once this factor is eliminated, the two side are not necessarily equal. Like saying that (0)(2) = (0)(3) means 2=3.

    That and the addition at the beginning is completely arbitrary.

  37. Lukas says:

    His equation is actually correct for study = fail and no = 1.
    But then if you follow the logic of translating multiplying a word by no (1) than there is no difference between no sth and sth.

  38. drewbaka says:

    when i read this i imagine the poster talking like ralph wiggum… he said maths.

    • Sesoron says:

      Um. That’s what they call it in the UK. In the US, the abbreviation for “mathematics” is “math”, while in the UK it’s “maths”, which is logical (at least as far as any abbreviations are logical) because “mathematics” is a natural plural.

      • Damenuendo says:

        Not to be picky, but teeeechnically mathematics is an uncount noun, just like athletics. That being said, despite living in Canada (where math is primarily used), maths really is a more logical abbreviation.

        • Damenuendo says:

          Actually, having said that, uncount nouns use a singular verb tense, so really math makes more sense as an abbreviation, a phrase such as “Math is fun!” sounds more natural than “Maths is fun!”. Or maybe it just seems that way to me because I grew up with the abbreviation math.

      • lol says:

        but mathemathic is one subject, unless you referred to addmath.science math, bla bla math and so on….

      • lol says:

        how bout grammar?

        GrammarS?!?

        • Mathematician says:

          when you find someone who claims to be a ‘grammartician’, then you can use that example. different words have different endings… its a language people like to refer to as English… guess where it came from…. also….. if your saying that you have “mathematic next period”, i think you really need to find that grammartician.

          • Saru says:

            As an American student who uses the proper terminology… I am ashamed in my peers for being ignorant of their own language. I hereby apologize to any British readers having to argue with idiots who believe that “mathematic” is a subject to be taught in school.

            To further explain to the those idiots, it is mathematics (with an S) because mathematics refers to all fields of maths, such as calculus, algebra, geometry, etc. But right now, I encourage you to study English. Not maths.

  39. They need a velvet rope up in front of the Facebook nightclub.

  40. angelatheist says:

    it would seem to me that the opposite of no fail is fail thus
    no fail + fail = 0
    no fail = -fail
    no = -1
    now we can see that (no + 1) = 0 thus in order to reach study = fail you divided by 0.
    Therefore no matter what you do, you fail.
    Q.E.D.

  41. KC says:

    I felt like I had to comment on this being a nerdy and all…. lol. The problem with the formula is that you use associative property when that property does not apply to inverses.
    !Study = Fail, & Study = !Fail
    if you add the two equations you get
    !Study + Study = !Fail + Fail. X + !X = 1(aka true)
    therefore you get
    1=1

  42. Lilepsilon says:

    if STUDY is 1*STUDY… then NO STUDY is actually -1*STUDY. So (NO+1) = 0, and canceling (NO+1) would be dividing by zero. o_O

  43. brittany says:

    well actually that wasnt really a burn because he changed the value of the equation. you cant change the value of the equation and then say that your assuming that the equation is correct because then you literally going in circles. but then again i dont study and pass so..muahahahahahahahaha

  44. Nerd central says:

    Haha this status appeared on my fb newsfeed after our calc final! Gota love Columbia’s geekiness!

  45. smitty says:

    MAJOR PWNAGE

  46. QED says:

    First, the original set of equations contain a contradiction without any extra work. One of the initial assumptions is that Study = No Fail, and then we “prove” that Study = Fail. Transitivity tells us that we then have Fail = No Fail, which is a contradiction.

    Second, the QED is always last, after the conclusion.

  47. Alexandria (I am also an Adult-Woman) says:

    actually…. if I study, I fail… if I don’t study, I pass with flying colors… go figure.

  48. Frederik says:

    They got it all wrong!
    this is a logic-ism based proof!
    After all Fail does not imply a no study, and a pass does not imply study. We’ve all passed a course without studying, so this is the 3 statements, since we assume classical logic, and we either study, or do not study:
    ~: not, S: Study, F: Fail, P: Pass,

    ~S -> F S -> P
    ————————-
    F P ~S Or S
    ——————————————–
    F or P

    Concluding that, if we either study or not study, we can fail or pass…
    Meaning nothing has changed what we already knew…
    Whatever you do, it is still mostly unpredictable…
    (my Ex was a mathematician, had to bulk up when there was some dispute with logic… :S)

  49. ClearWater says:

    Actually, it’s because No = -1, so both of them are dividing by zero, both of them fail.

    Also the premise that ‘Study = No Fail’ is debatable.

  50. Icarus says:

    Aside from the assumption of commutativity, Ja failed for one very simple reason. Let’s abstract this a bit with

    studying = x.

    Since not studying is the opposite of studying, let

    not studying = -x.

    Similarly, let
    fail=y
    not fail=-y.

    From there it’s clear to see that

    x-x=y-y
    => (1-1)x = (1-1)y
    => 0x=0y.

    And so since division by zero is undefined, he receives his error.

  51. Diego says:

    But if the second guy states that
    Pass = No Fail,
    shouldn’t
    Fail = Pass/No
    instead od
    Fail = No Pass?

  52. dXter says:

    anyway, we can assume that ‘No’ is an additive inverse operator, aka -1. so he just divided by zero. (No + 1)

  53. Phlip says:

    To take it another way:
    Substitute the first line into the second:
    No No Fail = Fail
    No² = 1
    No = 1 or -1
    Now, clearly the option of “No = 1″ is at odds with the definition of the word, so we’ll assume No = -1.

    Now, that means when the poster divided both sides of his equation by (No+1), they were actually dividing by zero.

    Remember, kids: ab=ac -> b=c or a=0. Ignoring that second part is the path to brokenness.

    Technically my own proof falls into that as it divides both sides by Fail, so the next like should read “No² = 1 or Fail = 0″… the complete space of all solutions, mathematically, to the stated equations is the union of three lines:
    * Fail = Study = 0; No is unrestricted
    * Fail = Study; No = 1
    * Fail = -Study; No = -1

    • ComeOn says:

      Actually No = 1
      Initial Equation
      No Study = Fail
      Study = No Fail per Symmetric Property No Fail = Study

      So
      (No Study = Fail)
      + (No Fail = Study)
      ————————
      No Study + No Fail = Fail + Study

      No(Study + Fail) = (Study + Fail)

      No = 1

  54. Pat says:

    Proof by contradiction, facebook style. Nice. I think that’s something I’d do, except I wouldn’t have thought of the last line.

    Well played sir.

  55. Henker says:

    Indeed, the main fault is the beginning. The “+” in “(no study = fail) + (study=fail)” does not make any sense (what is the sum of two assumptions?).
    So Ja deduced a nonsense conclusion from an undefined expression.

    A correct assumption would be “(no study = fail) AND (study=fail)” and it’s onvious that you can’t get a nonsense conclusion from that.

    Yes, I am bored a little bit. Why do you ask? :D

  56. Jules says:

    i still don’t understand math…

  57. Joe says:

    No, MATHS is more logical because its (math)ematic(s). You don’t call grammar grammars because grammar isn’t short for anything else thats plural.
    DERP

  58. ANONYMOUS says:

    I solved math:

    (No study = Facebook)
    + (Study = No facebook)
    —————————–
    (No Study + Study) = (Facebook + No Facebook)

    -> (No + 1)Study = (No + 1)Facebook
    Q.E.D. (Study = Facebook)
    :)

  59. Inestine says:

    that would actually
    study^-1 = fail
    study = fail^-1

    1/study = fail
    study = 1/fail

    so these are just different ways to represent the same thing

  60. Lagerbaer says:

    The problem is that dividing by (No + 1) on both sides is illegal since you must prior to that exclude the case that you are dividing by zero. And we know only Chuck Norris can divide by zero.

    Especially if we agree that No = -1, we see that what the equation says is “0 = 0″ which is rather trivial and doesn’t tell anything about the relation between study and fail.

  61. Wannabe MarkTwain says:

    Cmon people, this is simple math..
    (Ja) is inevitably correct.

    He starts by explaining…..
    (No Study = Fail) X (Study = No Fail) which is equivalent to…..

    (No Study X Study) = (Fail x No Fail). Then precisely divide both sides by the word (No).

    Which then results in (Study x Study) = (Fail x Fail)

    The result simplified = 2Study = 2Fail

    Afterword.. Divide both sides by 2.

    Leaving you with the prominent result Study = Fail.

    Although the retarded algebra is completely logical to the fullest extent, you should take into consideration another equation.

    (Facebook + Homework) = (Fail)

    Students of mine consider this a tedious theory, but let me prove to you that this is wrong.

    Facebook + Homework = Fail. Then divide both sides with the letter Fa.

    cebook + Homework = il. The (i) presented in this equation is an imaginary number, aka = -1.

    cebook + homework = -L Then you detonate the entire question, leaving you with…

    Book + Homework = -Love/Crappy education.

    • Icarus says:

      3*3 !=2*3

      So if

      (Study)^2 =(Fail)^2 then
      Study = +/- Fail.

      So at last we come to the grand truth. If you study, you’ll either pass, or you will fail.

  62. milkduds says:

    discrete mathematics ftw

  63. Karin says:

    I love these people.

  64. RathsRuin says:

    divide by zero=solved

  65. Tanner says:

    Actually, it’s screwed up from the beginning.
    (No Study)=Fail and Study=(No Fail)
    Study=(Fail-No) and Study=No+Fail
    Study=(-No+Fail) and Study=No+Fail
    *Law of substitution*
    -No+Fail=No+Fail
    Fail=2*No+Fail
    0=2*No
    No=0
    Therefore, taking our original set of equations:
    Study=No+Fail and No Study=Fail
    Study=Fail and Study=Fail
    However, the “No” in front of Fail in (Study=No+Fail) implies that Study=/=Fail
    Ergo, Study=Fail and Study=/=Fail
    False.
    Q.E.D.

  66. Ghost says:

    This actually isn’t logical at all therefor it isn’t a valid arguement.

  67. HvsL says:

    Study is a really weird looking word when you write it that many times. . .

    • LexiLove says:

      hahaha It is… I’m getting dizzy, in fact…
      I hate this stuff. Geometry, right? Proofs n stuff. I could go kill myself right now. Yeah… that’ll work.

  68. Coma says:

    This discussion involves a lot of people not getting laid

  69. jpless says:

    Actually, he hasn’t failed. He’s only invoked the principle of explosion. Now ANYTHING is possible!

  70. Ariel says:

    These people have WAY too much math on their hands.

  71. Math kid says:

    i didnt read the past comments so im not sure if this was said but technically his equation is correct because he is using 2 opposing variables making it a good statement and the third comment down is using a different variable in turn just making another equivalent to study. So Kudos on the equation

  72. Zephyr says:

    Holy crap I know the people who posted this all, this is hilarious.

  73. Angel says:

    I don’t believe that the distributive property applies here.

  74. Cross says:

    How to keep your virginity

  75. Anaslex says:

    This simple lazy boy has sparked a wholly illogical debate .. what is the probability he will pass anything other than water? … Most enjoyable nonsense Q.E.muthaf*ckinD. lol

  76. Josheva says:

    He divided by zero because No = -1

  77. euan says:

    instead of wasting time working that out why not just STUDY SOME F**KING MATHS!

  78. mark says:

    The mistake is to suppose that No study=Fail and Study=No Fail. As long as this equation gets some logical inconsistences such as Study=Fail=NO Fail, we can assume the first equality is not true. The only case It’d be true is if we supposed that [No=-1] and Study=Fail=0. As long as study or fail are something (so they’re no zero), Study is not equal to Fail, and the first equality gets wrong.
    Conclusion: You can’t express real life mathematically.

  79. mathelete says:

    No=-1, so you are dividing both sides by 0.
    Look at this:
    set x=0
    2x=3x
    2=3

    NO

  80. his problem is that he took (No study) which is ONE variable and he took both separate words and divided them, That’s like taking 12 and separating it into 1 and 2 as separate variables. No study is one things, 2 words, but one thing

  81. CassIEEE says:

    uhm, lol WUT. :O :)

  82. joseph uy says:

    kamo rai gi buang anah!!!!!!!!!!!!!!!!!!!!!!!!
