I think the issue comes with “division and multiplication”, and “addition and subtraction” Here, I see people saying “Brackets/Parenthesis > Division > Multiplication > Subtraction > Addition” when I was taught “Brackets/Parenthesis > Division or multiplication, left to right > Subtraction or addition, left to right”

This is clearly
5/(2x). If we write this the form that the OP uses:5/2x- it’s fucked beyond all recognition.
