Despite throwing yourselves into advanced mathematics, many of you lack comprehension of the fundamentals from your elementary days.

If a student of mine wrote anything that looked that dumb, I'd mark it incorrect. Parenthesis are there to be used, and used properly.

It's not ambiguous. It only is for high school kids.

The answer is 0, but anybody who doesn't get it correct isn't retarded. It's like missing the comma before writing "but"--nobody will ever mark you incorrect unless you're in that specific elementary school class because a dumb "equation" like that doesn't even exist.

sorry I understand polish notation only.
Is it (in reverse convention)
5 4 2 3 1 - x / - 6 + 7 - ; or
5 4 2 / 3 1 - x - 6 + 7 - ?

All this confusion would go away if you used a vinculum instead of an obelus.

I don't understand what 2(3-1) does but I estimate the number is within the -100 to 100 range.

Do people seriously not understand simple PEMDAS?

>5-4/2(3-1)+6-7
>5-4/2(2)+6-7
>5-2(2)+6-7
>5-4+6-7
>1+-1
>1-1=0

I am an american with public school education. If you do not get this you should be disgusted with yourself right now.

You say pemdas yet you perform division before multiplication. You have the acronym memorized yet refuse to understand what it means. Americuck education at its best.

Let's write it like a human would do
5-4
2.(3-1)
Then you subtract that to 6-7 that would be -1

Quoted By:

It's pretty easy to solve if you formulate it correctly in your head 5-4/2*(3-1)+6-7
You don't even need to know PEMDAS
If all you know is that you have to solve the parenthesis first then you can easily do it. What makes it ambiguous is the division signal that no one ever fucking uses.

Your answer is wrong:

>5-4/2(2)+6-7
You simply this to 5-4 it shoulld be 5-1 since 4/(2*2 ) = 1. Dumbass

no serious scientist nor mathematician uses this symbol ever, it's ambiguous as fuck and it was pretty much invented for limited mechanical devices such as typewriters and cheap LCD calculators. low quality thread.
