Oh man, I shot Marvin in the face.
I can't believe this thread is dragging for 4 pages lol

PEMDAS says that multiplication and division rank equally. left to right.How Do I Remember It All ... ? PEMDAS !
P Parentheses first
E Exponents (ie Powers and Square Roots, etc.)
MD Multiplication and Division (left-to-right)
AS Addition and Subtraction (left-to-right)
Divide and Multiply rank equally (and go left to right).
Add and Subtract rank equally (and go left to right)
Yes, and you need to learn your crap. Your math is weak.
You're a PEMDAS'er and I have an old link to implicit multiplication in my mind. Just because I posted to a 2011;D forum doesn't mean I needed your little quick post before you edited it. After I posted my orig, I saw the way you worked it. I agree that your way works against the PEMDAS rules. I say there is an old rule that PEMDAS has tried to forget or push to the side.
I cannot comment on this multiplication difference as I have never experienced anyone else using a different system. I doubt mathematicians with an Erdos number have this problem, though. They probably have a well-defined system and stick to it. I would look for it if I was really so interested (but I'm not). PEMDAS is a well-defined rule-set for basic arithmetic and I have no reason to go against it.Multiplication comes first here. This is odd, really seems like a different system.
I really dont understand the reasoning behind the priorities. What do you gain with it?
It seems to me like a waste of time to fiddle around with that.
C uses PEMDAS, too, and it's a language far older than my puny lifespan of 19 years. I have no idea what you are talking about.You're a PEMDAS'er and I have an old link to implicit multiplication in my mind. Just because I posted to a 2011;D forum doesn't mean I needed your little quick post before you edited it. After I posted my orig, I saw the way you worked it.

Mnemonics are often used to help students remember the rules, but the rules taught by the use of acronyms can be misleading. In the United States the acronym PEMDAS is common. It stands for Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. ... Canada and Australia use BEDMAS. ...
These mnemonics may be misleading when written this way, especially if the user is not aware that multiplication and division are of equal precedence, as are addition and subtraction. Using any of the above rules in the order "addition first, subtraction afterward" would also give the wrong answer to the problem
Coding is my bread and butter. PEMDAS is used in programming languages. Any coder that tries to fight this convention usually gets hung from a rope off a 100-storey building.
I don't know about you, but I'm not willing to doubt a dude with that much experience in math and code.Degrees:MS Computer Science (2003)
