What easily-typeable do you default to for ≠?
@sabbatical I had a maths teacher say to use the last one when typing and the first is what Excel uses. Number 3 came from a look at Wikipedia!
@levisan @sabbatical `/=` means divide-by-and-replace.
@progo Ooh well that would be confusing if you weren't sure which it meant
@levisan the others besides != i’m not even sure i would interpret as ≠
