I've just realized that the division symbol (÷) represents a fraction where the numerator and denominator are represented as dots.
@espectalll I realized that too... in fifth grade or so.
@Vexatos you probably were paying more attention than I did at the time lol
:) It's a wonderful feeling when the notation ceases to be arbitrary.
A similar trick leads to cute faces and other oddities in some math contexts:
<•,•> or (•,•) for a metric or other map taking two variables. And |•| for norms.
I'm still partial to {(0,0)} though (set containing only the origin in dimension 2) just because whenever it comes up the chalkboard looks like it's covered in owls.
@espectalll that might just be a coincidence: the ÷ symbol was used to represent subtraction in many places
