A number minus itself is 0. The point of the equation was to show that treating infinity as a number yeilds invalid results.Lukeje said:You've made the assumption that infinity-infinity = 0...
O I see I was thinking he could not find the ^ on the keybord and used * (as I have naver seen * used in Math) vary sorrymadwarper said:
Haha, Fair Play!Sikratua said:Basic math rule. Unless there are parentheses, all multiplication and division is done BEFORE any addition or subtraction. The absence of parentheses meas that the last part, being 1*0, is done before the rest of the problem. So, the end of the problem is now +0.GoodGodItsAnOxymoron said:The * sign means multiply, plus why would it be 14?? anything multiplied by 0 equals 0Redingold said:If you meant for that divide sign to be a multiplication, it's sixteen. Otherwise, it's undefined.
EDIT: Wait a second, you snuck a minus sign in there, making it fourteen.
WHAT?!?!?!jamesmax said:how so?madwarper said:Ummm... What?jamesmax said:dam claim downmadwarper said:No, it's not. And, I'm not sure how you got it, and spelled the word, Wrong.jamesmax said:its 1 i dont know how so many got it rong
That answer is still wrong. The correct answer is 14.also ya i forgot BEDMAS so nvm on the 1 thing I think its 15 now
1+1+1+1+1+1+1+1+1+1-1+1+1+1+1+1+1*0=?
1+1+1+1+1+1+1+1+1+1 = 10
10-1 = 9
9+1+1+1+1+1=14
1*0 = 1
14+1 = 15
No, if you did it incorrectly, one the of answers you may get is 4.the.gill123 said:well if you use the proper mathematics of bidmas (Brackets, Indices, division, multiplication, addition and subtraction) it would answer 4.
Only if you define it as such. The set could be equally well defined withBloodSquirrel said:A number minus itself is 0. The point of the equation was to show that treating infinity as a number yeilds invalid results.Lukeje said:You've made the assumption that infinity-infinity = 0...
Wrong.the.gill123 said:ok here goes:
the - in the middle splits the sum up, the * at the end splits it up again so what this sium looks like, if you knew how to do maths, is (1+1+1+1+1+1+1+1+1+1)-(1+1+1+1+1+1)+(1*0)=4
A number minus itself not being 0 is inconsistent with basic arithmetic. You could just as easily define 3 - 3 = 3, but it simply doesn?t make sense within the system of math that we use.Lukeje said:Only if you define it as such. The field could be equally well defined with
infinity - infinity = infinity.

I KNOW THERE AREN'T! but thats how simple mathematics works, i have spent 3 years doing shitty overly complicated sums at uni, if it is to add up to 14, the sum needs rearanging so that it ends 1-1+1*0. this is because things are added before subtracted, and multiplied before added, so you work out the multiplication, then add up the first 10 1's then the 6 1's so simplified it looks like this 10-6+0 its not hard!madwarper said:Wrong.the.gill123 said:ok here goes:

THERE. ARE. NO. BRACKETS.
If you MUST add brackets, then it's (1)+(1)+(1)+(1)+(1)+(1)+(1)+(1)+(1)+(1)+(-1)+(1)+(1)+(1)+(1)+(1)+(1)*0
The equation is NOT (1)+(1)+(1)+(1)+(1)+(1)+(1)+(1)+(1)+(1)+(-1)+(-1)+(-1)+(-1)+(-1)+(-1)+(-1)*0
No, it's not.the.gill123 said:but thats how simple mathematics works,
Which just proves that modern universities are just overly expansive daycare.i have spent 3 years doing shitty overly complicated sums at uni,
Your understanding of math if wrong; Read the Order of Operations [http://en.wikipedia.org/wiki/Order_of_operations].if it is to add up to 14, the sum needs rearanging so that it ends 1-1+1*0. this is because things are added before subtracted, and multiplied before added, so you work out the multiplication, then add up the first 10 1's then the 6 1's so simplified it looks like this 10-6+0 its not hard!
thats my point, you DO have diffrent answers depending on how a sum is written, i was taught it in primary school, again its basic mathematic principlesMidgeamoo said:What most people don't understand is it is:the.gill123 said:well if you use the proper mathematics of bidmas (Brackets, Indices, division, multiplication, addition and subtraction) it would answer 4.
brackets
indices
division/multiplication
addition/subtraction
If they weren't paired up like that then you could have the same sums equalling different things depending on how you arranged them.
Is this killing any maths students a little inside seeing people misunderstanding basic addition?

not on short answers, but 8+4-2+3 will give a diffrent answer to 8+4+3-2 because you work out the addition, 8+4 and 2+3 and subtract them, thats how it works, you block groups of numbers together that have not been broken up by a diffrent mathematical symbol. thats why typing 8+4-2+3 into a simple calculator will give a diffrent answer to a proper scientific one.madwarper said:a) You completely missed Midgeamoo's point.the.gill123 said:thats my point, you DO have diffrent answers depending on how a sum is written, i was taught it in primary school, again its basic mathematic principlesMidgeamoo said:If they weren't paired up like that then you could have the same sums equalling different things depending on how you arranged them.
b) The point you are making is wrong.
[4 + 2 - 3] is the SAME as [4 - 3 + 2]. Shifting around the -3 and +2 does NOT offer different results.
That would be true if people were just getting it wrong because they missed the -1.Tdc2182 said:Like I said in the last thread that did this, it doesn't prove anything about intelligence. It's designed to trick you.
It's all about attention to detail.
