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.

Surely you mean 5318008.

Excuse me, but self respecting mathematicians calculate it properly.

Now let's see, it was Dolly Parton had...

Math articles on Wikipedia really need a prerequisite section.

Shaka, when the walls fell.

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

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

That's A³

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. 😅
