the worst order of operations thing imo is with the denominator in division, many people say that 1/4x should be read as (1/4) * x and not 1/(4x), although I think this is usually the less popular option in polls
apparently wolfram alpha does it that way, as well as most newer graphing calculators (TI switched between the ti-82 and ti-83)

Depends on how many adults have forgotten the rules, since that’s what the poll is really tracking. Students have no issue with getting them correct (we’re talking like 98% correct).

In both cases they’re disobeying The Distributive Law, and so are demonstrably wrong
