5/9/2011 7:06:53 AM this statement is far from the truth.  Eric Spoelstra is by far the most fortunate coach in NBA history, and he's only had Lebron for one year.  as far as Jackson goes, you can't argue with championships.  also, Jordan will tell you that he couldn't have done it without Jackson.  Kobe would say the same thing.  players don't make coaches good, but when you get the perfect fit you get amazing results.
4/28/2011 9:20:00 AM l33t?  don't you mean 1337?  ur such a n00b.  i have 1337 hax.
4/23/2011 7:21:55 PM if you're willing to drive a ways you could check out Granite Peak.  it's in wausau, wi.  definitely the largest in the area and probably the tallest.
4/16/2011 3:19:55 PM so much math fail.
4/16/2011 3:18:43 PM hahaha this is full of epic win!
4/15/2011 1:11:37 PM [/QUOTE] Wrong, Order of operations suggests that the inside of parentesis gets done first, then the multiply, then divide[/QUOTE] oh please get over yourself.
4/15/2011 12:45:06 PM haha that's flattering but there really is no right answer.  this problem can't be solved correctly because it was written with poor notation.  there's no way to tell for sure if it's 48/(2(9+3)) or (48/2)(9+3).
4/15/2011 8:06:14 AM actually, you can add implicit brackets because that is the correct way to solve it.  what you can't do is use elementary math to solve a complex math problem.  48/2(9+3) is the exact same thing as 48/(2(9+3)).  (48/2)*(9+3) is a completely different equation. any math teacher will tell you that 48/2(9+3) = 2.  they will also tell you that when a number is directly next to a parenthesis (or bracket), it should be multiplied (or distributed) first and foremost. the fact of the matter is the notation gives this one away.  using the symbol ÷ implies that everything before is is a singular number and it is divided by everything after it.  now, if the OP would have used the notation 48/2(9+3), this might actually be a debate.  there is no way to tell for sure if it is (48/2)*(9+3) or 48/(2(9+3)). are you trying to say my applied math degree means nothing? [/QUOTE] From what I read in your response, you agree with me.  Since the question was written with the ÷ symbol and not a slash, clearly there is one answer using order of operations.  Regardless, it has already been said that the question is flawed.  Why would you assume I am saying your applied math degree means nothing?  I said you don't need one to answer this question.  Do you think you need a math degree to answer this question? You shouldn't need people on the to validate your sense of worth.  your degree is worth as much as you get out of it and as much as you think it's worth.  Having said that, I use almost nothing of the math I've learned in school.  Consequently, I have forgotten all the math I've learned other than the math I need to use which is basic elementary math.[/QUOTE] i was just trolling really.  and i'll probably use very little of the math part of my degree in my career.
4/14/2011 5:24:28 PM the truth is, there is no correct answer because the notation is horrible.

4/14/2011 3:14:13 PM I wrote it in words first so the meaning would hopefully be more clear. Everyone agrees that it's ambiguous...and trying to type equations into a text box is just frustrating! Craig, looks like you did me one better with your x(y + z) = (xy + xz) example...I simplified a bit too much perhaps. Just my curiosity here - do you specialize in a particular field of math? [/QUOTE] i'm actually an applied math and computer science major.  i have enough math background to be a mathematician, and i can program software in just about any programming language.  i even have a concentration in video game design/programming.  basically i see everything like neo does in the matrix.
4/14/2011 2:52:56 PM Wow, dude.  Do you get all your information from Google?  I'd hate to have to be the one to point out that not everything on the Internet is true.  If you actually looked at the search result, you would have noticed Google actually changed the notation... Anyway, break the question into terms and it's pretty clear.  Forget about "adding extra parentheses".  BEDMAS/PEMDAS still exists, but just because multiplication and division are weighted equally does not mean you can move them around the equation at will. If a = 48 and b = 2(9+3) then 48/2(9+3) becomes a/b Even if a = 48 and b = (9+3) then 48/2(9+3) becomes a/2b If someone claims that a/2b is equal to (a/2) * b...well, that's beyond any help a forum can give. For reference, even my calculator gets this right (Sharp EL-520W) And if you need more evidence...try using fractions instead of whole numbers.  Divide one-quarter by one-quarter. Is it (1/4)/(1/4) or 1/4/1/4? If your answer to the first question was 288, in this case you would get one-sixteenth (0.0625).  If you can prove that x/x is something other than 1 (don't quote bs division by zero/infinity/etc)...well, you probably deserve a prize for undoing centuries of accepted math. [/QUOTE] couldn't have said it better myself. the answer is 2.  anyone is welcome to try to dispute this, however any applied math major such a myself will tell you that you're wrong. you MUST multiply 2 by the amount in the parenthesis before dividing 48 by the resulting quantity.  if you want to get 288 then you need to write it (48/2)(9+3). the correct order of operation: 1) 9+3 = 12 2) 2(12) = 24 3) 48/24 = 2 you're welcome. [/QUOTE] Nice edit by changing moron So if I added let's say * to the problem...48/2*(9+3) are you still going to do the 2*(9+3) part first?  [/QUOTE] i decided to be a little more nice 48/2*(9+3) is no longer the same equation.  48/2*(9+3) is the same as writing (48/2)*(9+3) or (48/2)(9+3).  people need to stop applying elementary math logic to a problem that is basically and algebraic equation. take for example the equation a/b(c+d) the correct order of operations is as follows: 1) b*c + b*d = bc + bd = (bc + bd) 2) a/(bc + bd) now take the equation a/b*(c+d) the correct order of operations is now: 1) c+d 2) a/b 3) (a/b)*(c+d) (for this order of operations, steps 1 and 2 are interchangeable) you have to think of this as an algebraic problem to get the correct answer.  you cannot work it from left to right.
