- notation - What does := mean? - Mathematics Stack Exchange
I have seen variants of these used by people who predate widespread knowledge of computer programming It would be interesting to know the earliest uses of a special symbol for this (and what symbols were chosen) An advantage of $:=$ is that it has a partner, $=:$, allowing it to distinguish which side is equal to the other by definition

- notation - Whats the difference between ≡ and ≣? - Mathematics . . .
$\begingroup$ $\equiv$ and similar variations are a generic symbols used to notate an equivalence relation $=$ is the specific equivalence relation "equals" that we are used to with sets and natural numbers and by extension is also the symbol used for equality of rational, real, complex numbers etc
- adding more symbols to the toolbox : r Revu - Reddit
You could also create new symbols using your markup tools and then save them to your symbol toolbox by using the right click and adding to toolbox If you like their symbols but want to slightly edit you could use the symbol, modify it with markups, and then group and save as a new symbol
- What does the small number on top of the square root symbol mean?
