THAT MATH DOESN'T COMPUTE!!!! |
| Jackalovski #170879 1 year ago |
this formula has been bothering me for ages then it sudenly came to me, in order for x-7 to equal 19+x, x would have to be two numbers, any number that's a square root is both a positive and a negative because a negative times a negative is a positive. so x is the square root of 169 |

Protip: If you didn't start elementary school math like this, then maybe AJ wouldn't have flunked it, given up and stayed unable to count to 6. Just sayin', Cherilee. |

Dysnumic, isn't it, Yeoseo? In the same vein of "Illiterate <-> Innumerate" and "Dyslexic <-> Dysnumic". :) |
| Jackalovski #170895 1 year ago |
maybe he was trying to spell dysnumic, then realised he was dyslexic, also, why is dyslexic so hard to spell? it seems so mean for when people have to write out there ilnesses. |

You all do realize that the math is already "done" for you on the board... |
| SpookEZ #170925 1 year ago |
What bothers ME is that the same character is used for both B and 6. |
| Roboshi #170948 1 year ago |
are these seperate equasions or are the values for b and x the same throughout. |
| SpookEZ #170961 1 year ago |
It's all one thing. B=13... and I have no clue what they are doing with X but apparently some dots times x are the square route of 169. Or. some dots times x equal B. |

The heck? That isn't even remotely close to being right.
I thought we had a deal. The math people don't try to do art, and the art people don't try to do math. Get back on your side of the line, art people! |
| Jackarunda #170975 1 year ago |
Very first equation:
x - 7 = 19 + x Which becomes x = 26 + x Which then is 0 = 26 Zero equals twenty-six. wat |

I'm a math major, and the step from the second line to the third line is false.

Confound these ponies and their fancy mathematics. |
| Steel_Thunder #170986 1 year ago |
math people please! Math functions differently in Equestria! Along with physics and a bunch of other things too! Equestrian Elementary school is more advanced than our human highschool. yes ponies are everything humans arent. cute, nature loving/caring, kind, friendly, unprejudiced, and smart. |
| furujiru #171001 1 year ago |
If you calculate backwards, X would be 13 on the left and -13 on the right. Could also be that one of the animators decided to troll us because s/he would know this would keep nerds for days. |

@JohnMagnum : Math major ? Me too. Nice to meet you. |
| makr #171042 1 year ago |
Before I found out what they were, I thought this was the sort of thing that imaginary numbers would solve. Then I learned a while later what they actually were and felt ripped off. |
| Jackalovski #171067 1 year ago |
@JohnMagnum ok, so i may have rushed the workings out because of the lack of space, but i still hold it to be corect, the square root of 169 is plus or minus 13 and if you put into the equasion:
13-7=19-13 both sides equal 6 you could try -13-7=19+13, because they're both still values of root 169 but it doesnt add up, this does not invalidate the original which does add up. |

I'm pretty sure you're not allowed to use variables like that. |

It should be 19 - x. |
| Anonymous #171743 1 year ago |
haha it's kind of fine
line 2 is obviously valid line 3 asserts that x is simultaneously some number and also (that number * (-1)) aka the root of a square. i'm not sure if that's a valid assumption to make unless you already know the answer but considering that's the only way to make it work it seems fair enough? |
| Heartmend #172012 1 year ago |
I always thought of it as a way to test the fillies' and colts' understanding. "What's wrong with these equations?" |
| Anonymous #172976 1 year ago |
0=26
0=26=2b or b = 13, 18.7r=b not-quite-triforce+2X=2b, or=26, so nqt/2+x=13 b=13 , nqtX = 10.81665 x=16/nqt so 16 = 10.81665 |

In the first equation, x=x+26.
WHAT THE FUCK? |
| Anonymous #177550 1 year ago |
The three-dot symbol ∴ is shorthand for "therefore".
This problem is predicated on the fact that when you take the square root of any positive number, the result is actually "plus or minus" - that is, there are two solutions to the square root. Basic example: x = sqrt(4) ∴x = 2 or -2. (i.e., x = +/- 2.) This is true because 2^2 = 2 * 2 = 4, and -2^2 = -2 * -2 = 4. So the equation x - 7 = 19 + x is true if you take x = sqrt(169), NOT x = 13, because sqrt(169) has two solutions: 13 and -13. Take x to be the positive square root for the left-hand side and x to be the negative square root for the right-hand side and the equation solves to true: x - 7 = 19 + x (given) (13) - 7 = 19 + (-13) (substituting 13 and -13) ∴6 = 6. (simplify) However, one of the steps taken to solve this problem as shown in the image make no sense to me. How does: x - x = 26 become: +x - -x = 26 At first glance I thought it was a substitution of -x for x, but then you'd get: -x - -x = 26, instead of: +x - -x = 26, as shown in the image. The only way I'd arrive at this is if I knew the answer beforehand. I'm a 20yo college student, having taken and passed Calc 2 and Discrete Maths courses, and taken and failed an advanced linear algebra course (gonna retake it come next semester), but I've not figured out the logic behind the above step. Hopefully a /b/rony or a /co/lt with more maths experience can jump in and explain this one. |
| Anonymous #191807 1 year ago |
the +x - -x = 26 is to assert that the answer must be the root of a square.
it takes x - x = 26 from simplification of line one, then determines that x must be simultaneously some number and that number * -1 |

Fuck bronies are awesome, when I first saw the white board my brain fried, but then reading through here I think I can understand what she was trying to get at. Only issue being is that yeah 13 - 7 = 19 - 13 however the original equation is x - 7 = 19 + x.
Now it is true that the sqrt(169) = +/- 13. However, you can't take some positive and some negative. Because 13 * -13 = -169, so I think the most plausible explanation is that Cheerilee mis-wrote the equation at the beginning of an impromptu lecture on algebra. Since the fillies didn't know what the fuck she was going on about they didn't correct her. |
