÷ could be a minus sign

No it couldn't.

https://en.wikipedia.org/wiki/Division_sign?wprov=sfla1

Did you check the reference? It says % can be used as a minus sign, not the obelus. Welcome to what happens when you're next-door neighbour Joe Blow can edit Wikipedia.

Yes I did, on page 243:

It was employed in the Philosophical Transactions by the Dutch astronomer N. Cruquius; ÷ is found in Hübsch and Crusius. It was used very frequently as the symbol for subtraction and ``minus´´ in the Maandelykse Mathematische Liefbebbery, Purmerende (1754-69)
