Glad for your support. One major disconnect here is that people view the original expression however they want, rather than viewing it as an input to a computer/calculator. There are rules and syntax.

There are rules and syntax.

There have to be because machines are only as smart as we make them. (Computer programmer here.) Ambiguity leads to problems like this and if we want to tell a computer or calculator that we want certain multiplicative operations to take precedence over others, we must add other parentheses. I think that also can be said about how humans solve the equation because if it was this...

48÷(2(9+3))

I'd be firmly on the 2 side. As of yet, implicit multiplication does not trump explicit multiplication, they are equal, for most standards.
