For most normal people, the MD and AS are interchangeable. However, this is notarized in a really stupid way which doesn't let you see whether it's (6/2)(2+1) or 6/(2(2+1)). How would we write it out on paper? who the hell knows? If we're going off of the strict sequence of PEMDAS, it would be 1 because
6/(2x3)=6/6=1

According to algebrahelp.com, all of my past high school math teachers, and all of my past math books, step three of the order of operations is "...Multiplication and Division -- Simplify multiplication and division in the order that they appear from left to right..." -http://www.algebrahelp.com/lessons/simplifying/oops/

I've heard both ways, that the MD/AS are done left to right and that it's strictly PEMDAS when in doubt. I choose the strict PEMDAS just because it's easier to remember.
Oh, and how to transcendential functions fit in? sin, cos, tan and the whatnot? After you apply the sin/cos/tan/whatnot, is it considered between E and M?

Hold up a minute. It's both guys. Both calculators have the correct answer for the problem they were given.
The TI-82 says:
6/2(2+1)
The calculator thinks 6/2 is a fraction, not a quotient. 6/2 is 3. So technically, 3(2+1) = 9
The Casio says:
6(division sign)2(2+1)
In this case, PEMDAS applies
*sorry I don't have a division sign*

Ok people. First: you do what is inside the parentheses first. You are left with 6 / 2 * 3. On this situation, you would solve the problem from left to right. ( that's the rule )

If you really wanted to get into it, 9 is correct if you use pemdas. The Casio may have used pemdas but is on the mod4 (for example) setting, meaning subtract 4 as many times from the answer as possible without going negative. Therefore the answer would be 1. If it was mod3, then you would subtract 3 as many times as possible making the answer 0. Hope I didn't hurt yalls brains too much.

BEDMAS-Brackets, Exponents, Division, Multiplcation, Addition, Subtraction. You do what's in the brackets first then what's not and then multiply both of those things together to get the answer of 9

It's to do with how the calculators were programmed. As seen by the previous comments, it can be done two different ways. Always be sure to put brackets around everything.
