@mc the casio on the left is wrong, and most calculators, the vast majority, would disagree with it.
Splitting hairs (figuratively)
Yea I picked up on that too, it is a bit ambiguous.
I can say from personal expiernce that 1) no one ive ever met has done math that uses in-line division. They always make it stacked (like you do when writing) so any change of ambiguity is removed 2) if it is written on a single line they would never (outside of maybe physics those guys are wacky) consider multiplication and division to have different precedence.
