    What they actually see:

    convolution
    cross product
    dot product
    multiplication

      No. If a is a scalar, which it clearly is, it’s all multiplication. And there is no reason to use any of the first three. We say “three apples”, not “three x apples”.

      The irony is that this meme works in reverse for that. At least, in order of mind blowing as I refreshed my memory, it goes multiplication (very easy), dot (scalars easy), cross (vectors medium) and convolution (integrals hard).

      In fact, I never did the later two but convolution looks fun.

      I see multiplication in code, Cartesian product, multiplication, multiplication.

      I might not count as a mathematician though. If the * was supposed to be convolution the a should have been cursive.

        In latex if you are using * you better mean convolution

          Yes (actually \ast though?), but unless you’re a maniac in LaTeX latin letters referring to variables in a math environment are cursive (actually a math font I think). Therefore if I am reading a single sentence that may or may not have been made using TeX I tend towards not if variables are in a standard font.

      Numbers are all made up stuff, and they’re all the same. Here, lemme prove it; let a=b, and…

      a² = ab             // multiplying both sides by "a"
      2a² = a²+ab         // adding a² to both sides
      2a²-2ab = a²-ab     // subtracting 2ab from both sides
      2(a²-ab) = 1(a²-ab) // isolating (a²-ab)
      2 = 1               // dividing both sides by (a²-ab)
      

      From there you can prove any number is any number. 36=36 or 36=8 or 36=π.

      the trick

      If a=b, you can’t divide both sides by (a²-ab), because it’s a division by zero.

      Do you mean 36 = 18 there? Otherwise, I’m very confused. 😅

      Because the things like 3a are only for variables, not numbers.

      Yeah, when I found the meme template, it did say that, too, but I wasn’t sure if that information is actually helpful to someone reading alt text. Personally, I only know the guy from the memes. 😅
