I asked a Math teacher at the high school where I normally sub at to thoroughly explain the Order of Operations to me (PEMDAS)- P = Parenthesis; E = Exponents; M = Multiplication; D = Division; A = Addition; S= Subtraction. The way to remember it for me is: Please Excuse My Dear Aunt Sue.

He said that a common misunderstanding is people think that multiplication goes before division (because of the order) but that the multiplication and division are actually of equal prominence so the M doesn't necessarily go before the D and at that point you use the orderof the equation...So:

6 / 2 (1 + 2)

P = 1 + 2 = 3
D = 6/2 = 3
3/3 = 1

It's 9 but I sympathize with those who say 1, because I dislike when people write expressions or RockRaven Mar 2023 #6
if we replaced the "1" with an "x" it's easier for me to see the flow BlueWaveNeverEnd Mar 2023 #10
IMO the adoption of the assumed multiplication operator is where the muddle lies. RockRaven Mar 2023 #13
