It seems like some of the things you've learned basically refute things taught in high schools. Would you say that's true?

edit: not really refute. But just off really really quick research it looks like group theory is concerned with having an expansive outlook such that one term can equal different things, depending on how you look at it. I feel like there should be some sort of hint in high school math that what we're learning is not the only applicable method.

That's some good reading the thread you did there, Neapolitan.

@Story: hmmm... kinda. In many ways, not so much refute, as expand. A lot of stuff that's taught in schools is over-simplified in order to make it easy enough to teach. Having had first hand experience teaching, I don't blame them nor the system, but it's arguable that the system could be improved without making the courses too difficult.

For what its worth, I got 1.

I'm boggled by the philosophy that addition/subtraction and multiplication/division are interchangeable. Order of operations is something artificially created to avoid these issues. So why boggle the issue by saying

These laws, for ease of things like international space travel, will be iron clad...except for these parts here. Do this however the **** ya want. That part I'm lost on.

its 1.

I don't know if that is sarcasm I am better at Math than English. (I did my best not reiterate any point already made.) tbh I only scan through it, but the problem besides what operation goes first is how it is written, I only addressed how it would look like if it was written on paper. IF one looked at the problem considering "/" as opposed to "_______" then I thought it would clear some things up. Using the former would yield nine, using the latter would yield "one."


a/b*(c+d) =
If the equation was this:

it would be a÷[b×(c+d)]

Well, no one answer my question from earlier in the thread which was...

If we can agree that there isn't an inherent way to complete these problems and that the Order of Operations (OoO) is something to communicate more effectively as a globe, then why such flimsy guidelines sitting within the law?

It isn't logical to have order, where in there is disorder. Math is often seen as hard truths to achieve answers. But most of what we learn in math is philosophy. Its filled with theory and abstract constructs which we represent with numbers but you're not always told what you're multiplying or finding the radical root of.

All Oojay did, and myself since I got 1 also, was assign logical law to an area thats illogical. Why are certain ranks considered equal if there isn't an inherent way to find an answer, and we're making one up? If we're using PEMDAS, then it will determine rank where the system has failed.

Well, that seems to be the general consensus here.

Yeah I just read the title, did the problem, got 9.

Or 1 (if you do it the way you were taught your entire life, and the way that everyone you have ever interacted with in any mathematical environment have always done it).

I did it the way I was taught my entire life, and got 9. I also asked a friend of mine who is working on a Master's degree in mathematics what the solution is and guess what she said? Nine.
