BEDMAS/BODMAS says division before multiplication.
PEMDAS says multiplication before division.
Personally, I've always used BODMAS and it's never been wrong.
"The Director also sets the record straight on what would happen if oxygen masks were to drop from the ceiling: The passengers freak out with abandon, instead of continuing to chat amiably, as though lunch were being served, like they do on those in-flight safety videos."
its like adding and subtraction, they are interchangeable. if you do 2+4-3, 6-3 is the same as 2+1. 3*10/5: 30/5, or 3*2
Not really.
3/6*2 (by BEDMAS) = 1
3/6*2 (by PEMDAS) = 1/4
"The Director also sets the record straight on what would happen if oxygen masks were to drop from the ceiling: The passengers freak out with abandon, instead of continuing to chat amiably, as though lunch were being served, like they do on those in-flight safety videos."
Trust me. The rule is that mulitplication and division are NOT interchangeable. They are done in the order as they appear from left to right.
Yeah, they are definitely not interchangeable. Not sure about the left-right thing though. I'm pretty sure it's always "first division, then multiplication".
"The Director also sets the record straight on what would happen if oxygen masks were to drop from the ceiling: The passengers freak out with abandon, instead of continuing to chat amiably, as though lunch were being served, like they do on those in-flight safety videos."
No--it's definitely left to right. Not division first
let's say you have:
8/2*4*3*6/2
it equals 144 on my Ti-83
If you separate each step, it still equals 144
Just like addition and subtraction...left to right. (although that doesn't matter because it's commutative as long as you are adding negative numbers instead of subtracting positive numbers)
I say the answer is 9.5 (by first doing the divisions, then the multiplication and finally the addition).
Going by your logic of left to right it should be 4.5
The TI-83 seems to think I'm right.
"The Director also sets the record straight on what would happen if oxygen masks were to drop from the ceiling: The passengers freak out with abandon, instead of continuing to chat amiably, as though lunch were being served, like they do on those in-flight safety videos."
"The Director also sets the record straight on what would happen if oxygen masks were to drop from the ceiling: The passengers freak out with abandon, instead of continuing to chat amiably, as though lunch were being served, like they do on those in-flight safety videos."
Edit: and even though the left-right rule may be right, there is NO such instance where the "first division, then multiplication" rule doesn't work. Both of us are right.
"The Director also sets the record straight on what would happen if oxygen masks were to drop from the ceiling: The passengers freak out with abandon, instead of continuing to chat amiably, as though lunch were being served, like they do on those in-flight safety videos."
in BEDMAN and PEDMAS its this, Divi or Multi, which ever comes first, Add or sub, which ever comes first, but you must follow the rule of bracets and exponents
