3/7
I've even seen one say (of calculators) "sometimes it obeys (IM), sometimes it doesn't". That's because the calculator in question obeys Terms but NOT TDL, and it's behaviour is 100% consistent with that (but confusing to someone who has lumped them together as IM). They even went as far as claiming "PEMDAS is wrong", cos they were treating it like rules (whilst also #LoudlyNotUnderstandingThings like the actual rules TDL and Terms), and made up a new mnemonic, so let's look at mnemonics...

4/7 There are 4 mnemonics - BODMAS, BIDMAS, BEDMAS, and PEMDAS. The mnemonics aren't the rules, they are just a way to remember the rules, and, as per screenshot, it doesn't matter whether you do Division or Multiplication first, hence there is no conflict between the last and the first 3 (only in the mind of people who think they are the actual rules, and one or the other HAS TO be done first). This also debunks "it depends where you learnt" - the mnemonics aren't universal, but the rules are!
