- notation - What does := mean? - Mathematics Stack Exchange
$\begingroup$ I was aware of Pascal using :=, but not the others I think it is possible that the language designers of that time where influenced by maths (as has happened a number of times), but := is so far the only easily typable symbol mentioned here, so it is perfectly reasonable to assume it stems from programming languages in the first place

Another possible notation for the same relation is {\displaystyle A\ni x,} A\ni x, meaning "A contains x", though it is used less often The negation of set membership is denoted by the symbol "∉" Writing {\displaystyle x\notin A} x\notin A means that "x is not an element of A"
