Compassionate 2 years ago You guys will argue over anything. 6÷2(1+2)

1. hartnn

already argued over this...and consensus was its 6

2. hartnn

sorry 9

3. Compassionate

We are conversing, aren't we?

4. Kainui

It's 9. Next question.

5. Compassionate

I disagree that it's 9.

6. abb0t

Why is it 9 and not 13?

7. Compassionate

8. karatechopper

P E MD AS 6/2(1+2) 6/2(3) Left to right! MD 6/2=3 3(3)=9 My answer is 9

9. abb0t

$\int\limits_{0}^{L/2}dx_1\int\limits_{0}^{L/2} dx_2|\Psi(x_1, x_2)|^2=\int\limits_{0}^{L/2}dx_1\int\limits_{0}^{L/2}dx_2|\Psi_1^2(x_1)\Psi_2^2(x_2)-\Psi_1(x_1)\Psi_1(x_2)\Psi_2(x_1)|$ Which is $I_1I_2-I_{12}^2$ Where: $I_1= \int\limits \Psi_1^2(x)dx= \frac{ 1 }{ 2 }$ and $I_2= \int\limits \Psi_2^2(x)dx=\frac{ 1 }{ 2 }$ and $I_{1,2} = \int\limits\limits \Psi_1(x) \Psi_2(x)dx = \pm \frac{ \sqrt{51} }{ 2 }i$ Resulting in 13

11. karatechopper

WOAHH....@abb0t what did you bring in?!! I dont see any squiggles in the main problem!!

12. abb0t

pemdas is correct. It should be 9 though :) happy holidays all!

13. karatechopper

I said it was 9!! Happy that I am right!

14. FirstFrostByte

Ouch I have a headache... What in the world did you type @abb0t It's like in swahili...

15. karatechopper

Hahahah I couldn't even understand it.

16. AccessDenied

Looks like stuff from Quantum Mechanics, at least that's the only time I ever saw Psi used like that... Although I don't know much about the subject. :p

17. abb0t

Particle in a box :)

18. karatechopper

eh?

19. AthenaWolf

it could also be 1, if you distributed.... :)

20. abb0t

Haha. My initial thought was 1, but I 4got about PEMDAS.

21. UnkleRhaukus

$6÷2(1+2)=3(3)=9$

@Hero so you are saying you hate math

9

24. shubhamsrg

can we really directly assume that its not 2*3 together there? with that, it comes to be 1 :/

25. shubhamsrg

i see..didnt know that..hmm..

26. zaynahf
27. Compassionate

^ Lol. Didn't click.

28. zaynahf

Nothing risque or of that sort ;)

29. Compassionate

30. jennychan12

holy crap look at all these people viewing this...

31. HELP!!!!

they both suck

32. zaynahf
33. Compassionate

We are conversing, aren't me?

34. zaynahf

Yes, yes me am.

35. Compassionate

The answer is 6. Deal with it.

36. zaynahf
37. Compassionate
38. zaynahf

My gifs went to sleep. In other words, too lazy to argue.

39. Compassionate

In others words, you lose.

40. zaynahf

9

41. Compassionate

6

42. Kainui
43. Compassionate

Wolfram is obviously wrong.

44. Mathmuse

@Compassionate i'm having trouble understanding what your trying to achieve by being difficult...were you not loved as a child?

45. zaynahf
46. N00bstyle

So...to conclude: if a person asks this or writes this down, he has to formulate it better! Use another set of brackets.

47. Compassionate

I was molested by a reindeer. Don't bring up the bad memories. It's 6.

48. zaynahf
49. Compassionate
50. Kainui

I kinda didn't like compassionate, but now I actually don't mind him cause he's actually fairly mediocre at trollin'.

51. Compassionate
52. Mathmuse

Yeah, trolling isn't really trolling when it's transparent

53. Kainui

Unless I'm also trollin'.

54. Compassionate

ITT: Trolls trolling trolls who were originally meant to be trolled by trolls.

55. Kainui

d'ah!

56. Mathmuse

Zzzzz

57. Compassionate

Cary on my wayward son.

the "sqiggles" are integrals :) i don't even know what he did... some math magic wala!

61. zaynahf
62. Compassionate

Rage.

63. jennychan12

@karatechopper the "sqiggles" are integrals :) i don't even know what he did... some math magic wala!

64. zaynahf

Ohyes

65. karatechopper

I know they are integrals. but i like to call them squiggles

66. jennychan12

haha oh sowwy but i really don't know what he did. i would say.... BS!!!!

67. Compassionate

We can call them squishies.

68. zaynahf
69. abb0t

squiggles!!!

70. Kainui

$\int\limits_{\int\limits_{\int\limits_{\int\limits_{}^{}}^{\int\limits_{}^{}}}^{\int\limits_{\int\limits_{}^{}}^{\int\limits_{}^{}}}}^{\int\limits_{\int\limits_{\int\limits_{}^{}}^{\int\limits_{}^{}}}^{\int\limits_{\int\limits_{}^{}}^{\int\limits_{}^{}}}}$

71. Edutopia

all this is is a poorly defined statement, but the convention is to go from left to right with MD

72. robtobey

Refer to the following with regard to operator precedence: http://en.cppreference.com/w/cpp/language/operator_precedence 6÷2(1+2) -> (6÷2)*(1+2) -> (3)*(1+2) ->3+6 -> 9
