B is the same as P then.

The British / Australian O is better than exponents though, because it includes all other options in more complicated equations so I guess it is a little more flexible.

Though in saying that, if you have an equation with multiple exponents and other functions you should probably know what to do with out a handy little mnemonic.

Am I completely wrong to think that you kind of count multiplication and division at "the same time"?

Kind of like this:
Parentheses
Exponent
Multiplication Division
Addition Subtraction

Either way if you do division before multiplication, or subtraction before addition, you still get the same answer?

The reason you have pemdas multiply before divide, is that most equations written down like 1+2/3*4 are ambiguous. So a standard operating procedure allows you to understand problems not written clearly.

no they're not, people just misinterpret them. the division operator will only effect one entity, brackets count as one object. a*b count as 2.
all equations of form a/b*c will always equal (a/b)*c regardless of how many calculators you can find that'll do it wrong.
