Well to be fair, it's not written correctly.

You're probably right. My e-sarcasm meter doesn't work sometimes.

The left to right hierarchy is arbitrary, as suggested, but as a result of the left to right standard, the operator is associated with the number to the right and operations are done on one number (Meaning result from previous operation or initiating number multiplied or divided by the number associated with the operator) at a time. Your addition of parenthesis here
quote:

(3x8)/(2x4)
actually changes the problem while here
quote:

3x(8/2)x4
it does not. So if you do an operation as such here are some possible results for 3x8/2x4

3x8 = 24 24/2 = 12 12x4 = 48 or

3/2 = 1.5 1.5x4 = 6 6x8 = 48 or

3x4 = 12 12X8 = 96 96/2 = 48

I used 3 as the initiator every time because it was simpler to do so. You could use any of the numbers to do so but have to keep in mind that the 2, since it is a divide by would actually initiate as 1/2 just as you could think of the 3 in the original layout as 1x3.

And now you see why it's simpler to just say left to right.

It does not change the problem at all. It says do the first or last argument before doing division. the second one says do division before doing the first or last argument. Nothing "changes". If multiplication and division are "equal" you have the right to do any of them first (again ignoring right to left and having no parenthesis). You are implying that the 2 is tied to the division. The 2 could be tied to the multiplication to 4 and the 8 may be just (8/1). I was pointing out the ambiguity and it is just that. ...ambiguous

When was you time? Order of operations has been around for as long as I've been doing math. we had questions like this on tests just to make sure we knew how to do them. I'm 54, now get off my lawn!

You can do any single operation in any order. What you are doing is changing the division by 2 into division by (2x4). That is how you are changing the problem. If you change the /2 to x0.5 then you can move things into any position. The key in understanding this is that the equation is written to be solved left to right so the expectation is, assuming all parenthesis and exponents have been resolved, the operation indicated will be performed on the next single number.

Am I explaining clearly? I often seem to fail at that.

Playing devils advocate here; it's a grade school function that applies all the way through HS & college... People forget shite. My judgement is for people who act like its for geniuses bc they struggle with it.

If you dont use it you lose it.
Even if you remember what PEMDAS stands for but forget to go left to right you get it wrong.
Or 6-3=3 I dont remember being taught left to right .

Maybe if the problem wasn't horribly written in an intentionally ambiguous way, then there wouldn't be any confusion.
