A typical scientific calculator didn’t have juxtaposition, so you’d have to enter 6÷2(1+2) as 6÷2×(1+2)

That's not true

you’d get 9 as the answer because ÷ and × have equal precedence and just go left to right

Well, more precisely you broke up the single term 2(1+2) into 2 terms - 2 and (1+2) - when you inserted the multiplication symbol, which sends the (1+2) from being in the denominator to being in the numerator. Terms are separated by operators and joined by grouping symbols.

I'm not sure what you're getting at with your source. I'm taking about physical, non-graphic scientific calculators from the 1990s.

Yep, exact same as the calculator in the linked thread. The expression entered was 6÷2(1+2).
