    How did you find CN?

    Oh wow, it was so long ago I can't even remember! I do remember that I stopped playing NationStates when I started playing CN, so maybe someone linked it on the NationStates forums.

    48/2(9+3) = ?

    It's not even a question of BODMAS really. It's more of a notation problem. I.e. Does 48/2(9+3) mean (48/2)(9+3) or 48/(2(9+3))? Or to put it more simply, if you saw 1/2x, would you interpret it as (1/2)x or 1/(2x)? If you were to see it handwritten on some maths notes, for example, I expect most people would probably interpret it as 1/(2x). However, if you're being strict, you should interpret it as (1/2)x, and similarly (48/2)(9+3). Once you've done the brackets, all that's left is multiplication and division. Since you can think of division as multiplication (e.g. dividing by 2 is the same as multiplying by 1/2), you can do division and multiplication in any order and the answer will be the same. So really, there's not much BODMAS involved in this. Some of the discussion I've seen on this question ends up at the following: BODMAS says to do brackets first, so 48/2(9+3) = 48/2*12 Now, based on what I said above, you should be able to do this in any order and get the same answer, right? Well... Doing the multiplication first: 48/2*12 = 48/24 = 2 Doing the division first: 48/2*12 = 24*12 = 288 So what happened here? Like I said, this is actually a question of notation. Take a step back and interpret the notation correctly: 48/2(9+3) = 48*(9+3)/2 = 48*12/2 And now it doesn't matter what order you do the multiplication/division in. You will always get 288. All the discussion about order of operations is just a red herring. It's your interpretation of notation which is important here. Always use brackets to make your equations as unambiguous as possible! (I'll be amazed if anyone bothers to read all of this!)

    Here's a decent article which actually provides some information... http://blogs.discovermagazine.com/badastronomy/2011/01/13/astrological-sign-of-the-times/

    Why haven't you selected any of the options? The "No Response" option is usually a lot worse than the others. You collected taxes on the 13th with a -4 happiness penalty, when it could have been just -$5.00 (equivalent to -2.5 happiness) if you had selected Option 1... As for the most recent event, just select Option 2, -10% land area. Those events aren't that bad really. Back in the day, I once had a string of bad luck with three or four -3 happiness events in a row. That set my nation development back by weeks.

    Cumulative Values of Whole Powers of Two

    Indeed, that's what he was saying initially. However, I think he was trying to make a more general statement when he observed that: But I think there's actually a typo in there and it should read N = (N-1)*2 + 2^5, which is connected to the statement "if a set of values for X starts out at 2^5" (Updated my first post with more stuff now).

    Cumulative Values of Whole Powers of Two

    This is a short post as I have to go out soon. I'll edit in some more stuff later (edit: done). I think I managed to get the gist of what your were trying to say, though the few typos you made and the lack of a clear conclusion didn't help The sequence of the powers of two is an example of a geometric progression (GP). A geometric series is the sum of a GP. What you've figured out is a forumula for the geometric series of this specific GP. A general forumula does exist for any geometric series: You can find more info on what the symbols mean etc. on the Wikipedia page I linked above. Putting that to one side, however, here's an easy way to see where your observations come from. Let Xn be the sum of 2k where k goes from 0 to n: Xn = 20 + 21 + ... + 2n As an example, let's take n=4: X4 = 20 + 21 + 22 + 23 + 24 If we factor out a 2, we get: X4 = 2(2-1 + 20 + 21 + 22 + 23) But, we can spot that: 20 + 21 + 22 + 23 = X3 Therefore, we can write X4 as: X4 = 2(2-1 + X3) = 2X3 + 20 In general, we can see that Xn = 2Xn-1 + 20, which is what you first observed. Now, lets define Yn as the sum of 2k where k goes from 5 to n: Yn = 25 + 26 + ... + 2n Take n=9 as an example: Y9 = 25 + 26 + 27 + 28 + 29 Following the same logic as before, we arrive at: Y4 = 2(24 + Y8) = 2Y8 + 25 And in general: Yn = 2Yn-1 + 25 To generalise this even further, we can say that if Zn is the sum of 2k from k=m to k=n, then: Zn = 2Zn-1 + 2m

    Require Data Plans

    o_O I actually had to read that 3 times before I understood what you were saying. In the interests of education, here's what it should have been: Also, while I'm here, I've noticed that you always type 'quiet' when you actually mean 'quite'. Do an advanced search for 'quiet' by author 'Kochers' to see what I mean. [insert witty joke about grammar nazism here]

    Suggestions for new topic forums?

    A "Look what I found" forum, where people post links to things they have found on the interwebs. Particularly good posts would be hard games with levels or random generators, for example, as they can generate a lot of discussion.
