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!

5/7 Note that "Brackets" means remove/solve/expand and simplify brackets. As we have seen this is taught in Year 7 (when we teach about coefficients of bracketed Terms). It does NOT mean "inside brackets", which is what's taught in Primary School (when bracketed Terms never have a coefficient), yet many people claim it does. I found it curious that so many people have a rock-solid memory of what they were taught in Primary School, but not High School, so I ran this poll https://dotnet.social/@SmartmanApps/110868343908844233
