Every one of these only makes me say “wouldn’t it be great if we did everything with RPN”?
÷ could be a minus sign, see: https://en.wikipedia.org/wiki/Division_sign?wprov=sfla1
Except that it has English text above it…
÷ could be a minus sign
No it couldn’t.
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)

You know the Facebook post is in English and from 2025, right? 😂
So order of operations is hard?
The issue normally with these “trick” questions is the ambiguous nature of that division sign (not so much a problem here) or people not knowing to just go left to right when all operators are of the same priority. A common mistake is to think division is prioritised above multiplication, when it actually has the same priority. Someone should have included some parenthesis in PEDMAS aka. PE(DM)(AS) 😄

There’s no “trick” - it’s a straight-out test of Maths knowledge.

Nothing ambiguous about it. The Term on the left divided by the Term on the right.

It’s not a mistake. You can do them in any order you want.
when it actually has the same priority
Which means you can do them in any order
