Common Core math question is Algebra!!!! *gasp*



  • Question:
    How do you get 10 from 8 + 5?

    Answer:
    You take 2 from 5 and add it to 10.

    But now you have another problem. Common core says to subtract you add up. So how do you take 2 from 5? You start with 2 and add 3 to get 5, so your answer is 3.

    But based on the pattern indicated above, how do you know you need 2? You have to subtract 8 from 10 So you start at 8 and add 2 to get 10, so your answer is 2. So let's start over

    How do you get 10 from 8 + 5?
    10 - 8 = ?
    8 + 1 = 9, 9 + 1 = 10
    1 + 1 = 2

    5 - 2 = ?
    2 + 1 = 3, 3 + 1 = 4, 4 + 1 = 5
    1 + 1 + 1 = 3

    8 + 5 = 10 + 3

    Answer
    You add 2 to 8 and take it from 5 to get 10.

    That's disguising algebra to teach addition.

    8 + 5 = 10 + x
    8 = 5 + x
    3 = x

    All that and you still haven't solved 8 + 5 = ?



  • And it continues

    How does Common Core teach multiplication?

    With integrating.

    2x3

    draw a rectangle map using squares

     _ _ _
    |_|_|_|
    |_|_|_|
    

    guess what that's like?

             |y
             |_ _ _
             |_|_|_|
    _ _ _ _ _|_|_|_|_ _x
    break up ranges of X to get more accurate estimation.
    y at x = 1 is 2
    y at x = 2 is 2
    y at x = 3 is 2

    Is this you or copied from the book?

    I'm pretty sure something's wrong there, but my eye keeps twitching too much to see what.



  • sorry, I chained additions.
    I'll break it up so you can read it.


  • BINNED

    It wasn't dickweedery attempt btw. Just wanted to make sure.

    I have seen some photos of this stuff already. If they genuinely did that in the book I wouldn't even be surprised, given how batshit insane it all is.



  • I wonder if they use matrices to teach division.


  • BINNED

    Might be. You have to transform it to be of order that is a multiple of 10 first, though.

    What the fuck is that I don't even

    I don't understand what "get 10 from 8 + 5" means. 8+5=13. "How do you get 10 from 13"? What kind of retarded question is that? You don't "get" 10 from 13. 13 is 13. You can take the difference of 3 and 13, and the result of that is 10, but you could also multiply 13 by 10/13! (13*10/13 = 10) Or divide by 13/10, add -3, raise to some power (smaller than 1), etc.

    Are you people teaching math wrong to children on purpose? Don't you know children will actually believe any dumb shit you tell them, and try to apply it to their lives? They don't understand sarcasm! Some poor fuck is going to grow up and think that's how math actually works!

    The first time I saw one of these it was something like "How does 6 + 8 make 10?", so the wording was even worse. My gut response when I saw that was "They don't. They make 14."

    I'm just waiting for someone to post one that says "How do you get 10 from 4 and 5?"



  • You intrigued me. How do you get 10 from 4 and 5?


    Well that was a disappointment.

    No, this is "Common Core". Supposedly, they are teaching kids the "shortcuts" instead of just teaching them arithmetic facts. The idea is that the kids first figure out how to get to the next multiple of ten, then add everything together because it's "easier".

    At least that's how I understand what they're doing. My kids are home schooled.


    This post is not an endorsement of the Common Core program or curriculum.

    I can only think of 2 possibilities:

    • Drugs. Lots of drugs.
    • 4 and 5 get a little freaky, and end up with a little 1.

    Edit: On the other hand, I guess the teacher could end up fearing for his life after that homework assignment. Do not recommend.

    For very large values of 4?



  • @abarker said:

    I have a shortcut for basic arithmetic work. It's in my phone's desktop, it opens up a calculator. Easy as pie. Oddly, it has no function for "get x from y".

    I know you are not endorsing it, so don't take it personally, but I'm pretty sure someone is sabotaging your education infrastructure from within. You might want to have that looked at.



  • @cvi said:

    4.5 is a large value of 4.



  • And 5.5 is a large value of 5

    4.5 + 5.5 = 10

    Answer:You take 2 from 5 and add it to 10.

    What age are your kids? Is this the kind of shit I have to look forward to? Because I will tell my child that it is perfectly OK to go back to school and tell their teacher this is bullshit.



  • I.e. Belgium teaching an Algebra class about Algebra, a Pre-calc class about Trig and a Geometry class about geometry. We could do all three at the same time. No way is that stupid or confusing!



  • Yeah.

    The question "How do you get 10 from 8 + 5?" is IMO best answered with "You don't.".



  • @tar said:

    My first reaction to the original question (well, first reaction after "Wat?!") was 8 + 5 = 1013.

    • Church
    • Activities with other home schooled kids every few days
    • Play dates with kids who aren't home schooled at least once a week
    • Activites at the park, science center, zoo, …

    You kind of have to, because you just turned 2 years of arithmetic into 4.

    I'd rather cut the Department of Education. It's not like they're doing any good. Not to mention that the existence of said department is an overreach of federal power, but that's a different discussion.

  • WRONG.

    You multiply by 10/13ths.



  • Okay smart guy,

    Assume the Black-Scholes framework. For a stock that pays dividends
    continuously at a rate proportional to its price, you are given:
    (i) The current stock price is 5.
    (ii) The stock’s volatility is 0.2.
    (iii) The continuously compounded expected rate of stock-price appreciation is
    5%.
    Consider a 2-year arithmetic average strike option. The strike price is
    $$
    A ( 2 ) = 1/2 [ S ( 1 )  S ( 2 )] .
    $$
    Calculate $Var[A(2)]$.

    Needs more mathjax.

    Wrong. Question is incomprehensible.



  • No, it's really not. 8 and 5 is 13. So how do you get 10 from 13? By subtracting 3.

    You understand elementary school students get this, right?



  • @Captain said:

    You understand elementary school students get this, right?

    So, no they don't.



  • So a particular elementary school student doesn't understand subtraction. Maybe that's why he's in school.



  • You can also get 4 when adding 8 + 5

    Take -1 from 5 and add it to 8
    (8 + (-1) = 7) then add 6.

    @Captain said:

    doesn't understand subtraction

    No, he doesn't know how to infer what the teacher is asking.
    He's assumed that the teacher would want the final answer, just like any other person would.

    I can show how you can get ANY number from 8 + 5 using the same logic.



  • No, the question fundamentally does not make sense. 8+5 is 13. You said it yourself. There is no way you can add the number 8 to the number 5 and get 10.



  • Sure you can. You have to subtract 3 once you've done your addition.
