  That’s not even an equation, just basic arithmetic

  Basic Algebra actually. Students aren’t taught the Distributive Law until they start on Algebra

  Technically not algebra, right? Algebra is where you move things around and solve for variables, and that kind of thing. This is just arithmetic.

    No, it actually is Algebra. The Distributive Law isn’t taught to students until they start on Algebra.

    This is just arithmetic

    There’s no a(b+c) in Arithmetic.

      I don’t think you’re right. The wiki page literally uses a similar equation as an example of “elementary arithmetic.” It also uses a similar one, but with variables, as an example in “elementary algebra.” That implies that yes, this is arithmetic, and the introduction of variables is what makes it algebra.

      It doesn’t matter what course finally teaches it to you. That could be just out of convenience, not by definition part of that domain. It’s been ages since I took it, though I could swear I learned this in pre-algebra (meaning before algebra), or earlier. I could be wrong on this though. Again, it’s been a very long time.

        I don’t think you’re right

        You don’t think Maths textbooks are right??

        The wiki page

        is full of disinformation. Note that they literally never cite any Maths textbooks

        as an example of “elementary arithmetic.”

        And whichever Joe Blow My Next Door Neighbour wrote that is wrong

        as an example in “elementary algebra.”

        Algebra isn’t taught until high school

        That implies that yes, this is arithmetic,

        No, anything with a(b+c) is Algebra, taught in Year 7

        the introduction of variables is what makes it algebra

        and the rules of Algebra, which includes a(b+c)=(ab+ac). There is no such rule in Arithmetic.

        It doesn’t matter what course finally teaches it to you

        It does if you’re going to argue over whether it’s Arithmetic or Algebra.

        not by definition part of that domain

        The Distributive Law is 100% part of Algebra. It’s one of the very first things taught.

        It’s been ages since I took it

        I teach it. We teach it to Year 7, at the start of Algebra

    You’re right, that’s what I meant. Fixed it, thanks!

  Fair enough, I’ve heard “math problem” and “math equation” used interchangeably.

  Also you would be surprised how many people do not know basic algebra, at least in the US rofl

    You. You are one of them bc you do not know what an equation is.

    There is no algebra here. This is arithmetic.

      Yes there is, 5(8-5).

      When I made my example, I used an algebraic expression, but yeah, the original question was arithmetic, sorry. Not very good at explaining things XD

  Algebra has horrible syntax. Way too much implications.

  source

  • Septimaeus@infosec.pub ⁨3⁩ ⁨weeks⁩ ago

    Implications or assignment? They didn’t specify notation.

      Umm, neither?? 😂

      They didn’t specify notation

      a(b+c)=(ab+ac) is taught in Algebra, The Distributive Law, it can’t mean anything else - it’s the reverse operation to Factorising ab+ac=a(b+c).

        I know. I was clowning on the dude mad about the arrows by offering one of numerous other meanings outside Boolean Algebra that sounded even more absurd in that context.
