Title: Math Problem Post by: Lumpybob on October 25, 2004, 05:07:34 AM 4+4+4x2=?
i wont tell the answer tilll the second page :shifty: Title: Math Problem Post by: PREATOR DEFIANT on October 25, 2004, 05:09:51 AM Answer appears to be 24 but there might be a hidden answer.
Title: Math Problem Post by: Lumpybob on October 25, 2004, 06:13:06 AM mmmmmmmmmmmmmmnmnmnmnmn..........................................................
Title: Math Problem Post by: Optec on October 25, 2004, 09:22:28 AM the answer ist 16
Title: Math Problem Post by: Detektor on October 25, 2004, 10:26:56 AM Quote the answer ist 16 I think so Title: Math Problem Post by: PREATOR DEFIANT on October 25, 2004, 11:54:17 AM If you follow the order of operations in algebra. I was going to do that but I was also hoping for a simpler answer.
Title: Math Problem Post by: Lt.Cdr.White on October 25, 2004, 02:29:59 PM I also think it's 16. I should have looked into this thread earlier...
Title: Math Problem Post by: -=B!G=-The Black Baron on October 25, 2004, 05:35:36 PM Lol of course its 16 :D:D:D
Title: Math Problem Post by: Sferimao on October 25, 2004, 05:36:41 PM The way it is written , it is 16.
Title: Math Problem Post by: Optec on October 25, 2004, 06:51:25 PM or 8+8x, if x is a parameter :) but 4x2=8x would be a very unusual manner of writing, well at least you can leave the multiplication sign out ;)
or is there still a trick we don't think about? Title: Math Problem Post by: Overlord/Zeich on October 25, 2004, 08:48:13 PM The answer seems to be 16. But if there is some trick to it, I don't see it.
Title: Math Problem Post by: [TD]Roach on October 25, 2004, 09:01:11 PM it's definately 16, X over rules + so
you have to calculate first 4x2 and then +4+4 Title: Math Problem Post by: cts006 on October 25, 2004, 09:11:09 PM Yah... id agree to 16 also.
Title: Math Problem Post by: Lumpybob on October 26, 2004, 03:23:09 AM hmmmmmmmmm........alot more replies than i expected! wow!
Title: Math Problem Post by: RFO Cairo1 on October 26, 2004, 03:26:07 AM ha ha ha ha told you alot of people would get it right it is 16 he thought he cuold trick you ha ha ha ha i can only laugh at you atempt to tric the guinus who started FO
Title: Math Problem Post by: Lumpybob on October 26, 2004, 03:27:45 AM that might be the wrong answer! there are two different answers. which one you get depends on how you work the problem out
Title: Math Problem Post by: Cmd.Paul on October 26, 2004, 04:03:48 AM 4+4+(4x2)
8 + 8 = 16 there is no other anwser Title: Math Problem Post by: Lumpybob on October 26, 2004, 04:07:02 AM yeah, but the idiots do it like this:
4+4+4x2=? 4+4+4=12 12x2=? ?=24 see? Title: Math Problem Post by: RFO Cairo1 on October 26, 2004, 04:09:40 AM uh oh i have to go jolan tru good bye yall se ya next time on duks of hasard
Title: Math Problem Post by: Cmd.Paul on October 26, 2004, 04:10:07 AM I know, however that is not the solution to the question, so logically there is only one good anwser; 16
Title: Math Problem Post by: [F-I-I]VAdm-MJP on October 26, 2004, 04:20:54 AM bingo. any one with basic algibra could tell its 16. Unless like statered before, X is a varible witch i think would be X= (-1.5) lol i might be wrong on that though. lol
Title: Math Problem Post by: Lumpybob on October 26, 2004, 04:23:38 AM exactally! i though of it to weed out the idiots in school. so far, only 3 people have goten it right since i started asking it 3 years ago. thats pathetic, and none of them were teachers
Title: Math Problem Post by: Sferimao on October 27, 2004, 02:32:38 PM There is only one correct answer to this (I won't call it even a problem) and that's 16.
Title: Math Problem Post by: [F-I-I]VAdm-MJP on October 27, 2004, 04:02:12 PM what school do you go to?
Title: Math Problem Post by: Cmd.Paul on October 27, 2004, 04:33:50 PM Quote what school do you go to? for retarded?no but seriously, perhaps the human mind doesn't think of algebra rules directly, we have the benefit of having it to read wich is an advantage Title: Math Problem Post by: [F-I-I]VAdm-MJP on October 27, 2004, 04:58:49 PM that is a good point, we did ahve it to read.
Title: Math Problem Post by: Cmd.Paul on October 27, 2004, 05:42:00 PM think about it, if someone askes you that same question you dont think with the algebra rules and just simple do + and stuff, when you read it you think like hey, with rules you do the x first
Title: Math Problem Post by: PREATOR DEFIANT on October 27, 2004, 10:19:05 PM Well the answer COULD be 24 to someone who hasen't taken algebra, but once you have it's fairly obvious it's 16.
Title: Math Problem Post by: cts006 on October 28, 2004, 12:07:27 AM I would asume (most of us) have passed grade 8?, cuz this is verry simple.
Title: Math Problem Post by: coolhandab on October 28, 2004, 05:06:18 AM Guys order of operations is 6th grade level math, tops. Please don't denigrate algebra by calling it that. Pre-algebra involves solving for a single variable you know.
Title: Math Problem Post by: Cmd.Paul on October 28, 2004, 12:33:57 PM yea ok, but it's all on paper mate, when someone ask you a quick question then, and you can say you don't but I know you do, want to try and solve it quickly and most likly say the wrong anwser BEFORE you go and think hey wait....you have to x first
Title: Math Problem Post by: Captain Neutron on October 28, 2004, 04:14:41 PM Typically, when writing math problems on a computer, unless your using microsoft equation editor or some other symbol writing software, * is the symbol for multiplication (since x is actually the symbol of a cross-product, at least in any higher level math class). So, the correct way to have asked the question would have been (being consistant, if x is a symbol, so to must be the ? mark)
4+4+4*x*2=? Now, I don't think you could solve this as originally stated. This is what is called a two by one system, and under specified (2 degrees of freedom?). Since if the x is unkown, so is the question mark. Rewriting to help explain, letting ?=y, 4+4+4*x*2=y. So, this is in fact a line, y=8*x+8 with a slope of 8 which crosses the y-axis at 8. So, as written originally, I think that any reasonable person when first looking at this problem would either say that the answer is 16 or underspecified. Or, which is far more likely, poorly written. :unsure: Title: Math Problem Post by: Cmd.Paul on October 28, 2004, 06:58:34 PM true, however this is just basic math not with variables and all
Title: Math Problem Post by: Lumpybob on October 28, 2004, 07:57:30 PM its a trick, you got to know order of operations to get it right
Title: Math Problem Post by: PREATOR DEFIANT on October 28, 2004, 11:33:01 PM I did know the order of operations but due to bobs... chatting, I didn't think he has been so far as to have been in algebra of some sort.
Title: Math Problem Post by: coolhandab on October 29, 2004, 01:31:44 AM Haha I love it, an underspecified first degree equation! One degree of freedom and zero constraint equations! I hadn't thought of that one, and I get the feeling neither did Bob.
Title: Math Problem Post by: Lumpybob on October 29, 2004, 03:22:17 AM huh? underspecified...........huh? :huh:
