Under normal interpretations of pemdas this is simply wrong, but it's ok. Left to right only applies very last, meaning the divisor operator must literally come after 2(4).

This isn't really one of the ambiguous ones but it's fair to consider it unclear.

Pemdas puts division and multiplication on the same level, so 34/22 is 12 not 3. Implicit multiplication is also multiplication. It's a question of convention, but by default, it's 16.

Incorrect, pemdas puts multiplication before division.

I always thought pemdas was more like P/E/MD/AS with MD and AS occurring left to right

This is how I was taught, but also people don't really use the Γ· symbol in algebra beyond like 6th grade

Yes they do, just pick up a high school Maths textbook (in a country which uses obelus rather than colon).
