Order of operations: PEMDAS or GEMA?

Better yet, you can draw them on the graph xD

I got 77147105 on normals. Then I got my hands on the scientific calculator, and trout got real. "My daddy is a cabby", "3 in a bed", "Bombay Mix", oh those were the days.

Wtf are you talking about?

Basically, it seems that the British among us have been taught BODMAS or PEDMAS, whereas the Americans have been taught PEMDAS or GEMA. GEMA is far too ambiguous and PEMDAS is far too incorrect. I think the teaching system is a little off there

I think GEMA helps drive home the point Multiplication and Division and Addition and Subtraction are the same thing.

But when it comes to the crunch of doing one or the other first, division always comes first and subtraction always comes first.

I do them alphabetically, because I like mingling linguistics with mathematics.

I thought it was left from right in whatever order that so happened to be :confused:

Noo, that's I'm confused here. I did maths until I was in uni (and some in uni) and they've always said you always do it Division -> Multiplication -> Subtraction -> Addition. That's why I'm baffled by the existance of PEMDAS..

Jess is totally right here; it's from left to right, the same way we read.

What if you're Arabic?

SADMEP?

Even the British method you mention still puts addition before subtraction, and breaks with what you say is the proper method of thought.

As Jess and myself mentioned before, you can put M/D or A/S in the same order of importance as long as you always work left to right.

At least that's the way I was taught, and that's why I got the answer of 9 each time whether I used PEMDAS or GEMA.

I was assuming that IDNAN's "DMSA" thing was just a mistake, and that he meant to write it as DMAS. Nonetheless, GEMA is not ambiguous, as BODMAS and all its partners state exactly the same thing. It's merely the language that is ambiguous, since BODMAS is a primary school term, whereas GEMA uses more advanced terminology.

Yeah, sorry, that was a mistake from me. Dissertations fry your brains kids! And I disagree with you Quin. GEMA uses advanced terminology? Grouping-Exponents-Multiplication-Addition(?) How is that more advanced than Brackets-Order-Division-Multiplication-Addition-Subtraction? Grouping is a far more childish term than brackets and it misses out two functions? But yeah, thinking about it (again, fried brain), Division and Multiplication do cancel out in which order they're done in. Still dislike the complete difference in the way everything has been taught

I like Grouping as opposed to Parenthesis because it's more vague. With Parenthesis you think of parenthesis and brackets and overlook the importance of the difference between a horizontal divider (a type of grouping) and a division sign.
