Can remember BODMAS, can’t really remember what it stands for or what it’s purpose is though.
I CAN remember what the following stand for and what their purposes are though:
Never Eat Shredded Wheat (or Naughty Elephants Squirt Water)
Richard Of Your Gave Battle In Vain
There is one for the planets but I can’t remember what the mnemonic is (The planets go Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Pluto though)
Got anything to add?
