So I was telling this guy Black Ops 2 is not only a game, it's also about math. "Let k be your number of kills , d the number of your deaths, then you are a noob if and only if: k < d, that is, k - d < 0, or: k/d - 1 < 0, in other words: k/d < 1, where the LHS is the so-called kills per deaths ratio." Then I was twisting the things for him saying "But I like the k - d < 0 form where you square both sides giving (k - d)^2 < 0, because then you can declare yourself a pro, no matter what. So, where did I go wrong? "

So, where did I go wrong?

...only one mistake ...you started talking about math and expected a result.

in other news ...british folk amongst us might have seen this ...I don't know

SmokeDef, that's too easy to say. The real solution is below.

You can only write that if both sides of the original inequality are positive (actually the LHS can be zero too!), ie. k - d >= 0 and 0 > 0, none of which are true. So it's not possible to obtain an equivalent inequality, only with certain information loss. Because the LHS gets multiplied by a negative number, ie. the sign of the LHS is reversed, hence the direction of the whole inequality has to be turned around too, ie. (k - d)^2 > 0, which is satisfied with any k and d, so we can no longer tell who's noob from there.

Anyway I'm not 100% pleased with the solution above, but I have no time to elaborate more on it at the moment.
