I hate myself for replying to this thread, but the use of the division symbol implies the slash is a fraction bar.
No, it doesn't, only parentheses would imply that a division slash is a fraction bar.
A division sign and a slash have the same effect.
Unless you also expect people to guess as to whether or not the "9-3" and/or the "+1" are also part of the same fraction, which they aren't.

Why go out of your way to use the division sign on a computer keyboard if the slash means the same thing? If you're going to be cute, I'm going to be cute.

Ignoring order of operations isn't cute, it's just wrong. Without grouping symbols, the answer is 9.

As lsuboo stated, the +1 could fall under the fraction then it becomes 1/4, and the answer is now -3.

Not even going to wade into this problem, but has anyone noticed how all of the most heated math problems on the OT usually have at least one division sign and no parenthesis?
Just seems to be a common trend...

Actually, 9-3÷1/3+1 would group as (9-3÷1)/(3+1).

You should have seen the original problem OP posted. Absolutely no way to get an answer other than 9, and still people arguing about it.
Had one genius saying we need to worry about intent before answering a math problem. This thread has been money.

To intentionally be a dickhead and troll Facebook and message boards.
There is no such thing in math as a "fraction bar." That is a term by used by grade school teachers to teach grade school students who are just getting their feet wet with this stuff. 1/3 is a mathematical expression.

How did you come up with that arbitrary grouping?

No, it wouldn't.
It wouldn't group at all.
However, (9-3÷1)/(3+1) at the very least would be more correct (based on historical math syntax) than 9-3÷(1/3)+1.

It makes sense, unlike 9-3÷1/(3+1) that others suggested could be a valid alternative interpretation. One could make the precedence of slash lower than the other operators and write a grammar for this hypothetical system.

No it doesn't. There are no grouping symbols, so why randomly pick that grouping?

There is only one "interpretation." And that results in an answer of 9. Anything else is making assumptions that change the problem.

It makes sense, and it isn't random. Go back and read the discussion.

You don't get to just decide where to add parentheses to a math problem. The problem is what the problem is.Posted on 9/6/17 at 11:36 am to LNCHBOX

Historically, that could be one way to look at it, with everything to the left of the / as the numerator, and everything to right as the denominator.
That's an outdated approach though, and is no longer a valid solution.

Actually, 9-3÷1/3+1 would group as (9-3÷1)/(3+1).

When was it ever a valid solution to randomly group shite together in a math problem?

I didn't say anything about randomly grouping.
And I'm talking 100 years ago... so like I said... no longer a valid solution.
