Within that picture, the answer is 1, I agree. Fraction bars are considered a grouping symbol.
It just seems to me that since there is a ÷ AND a / in the equation, that it implies that one means to divide and the other is for a fraction
That’s how I interpreted it at least

The only setting in which a question would be worded this way would be on the internet to incite debate.

I don't agree due to the shitty structure of the problem, which is the whole point of this stupid thread. Stop saying there is only one "right" way. The whole point is that there isn't.
I bet you think there's more than 2 genders too huh?

No you don’t. Stupid people make stupid decisions. You may know 1 stupid millionaire; however you do not know a whole lot of stupid millionaires.

Nope. Great response though.

Are they going to say you're not stubborn as shite in this thread at the end?

That requires an assumption the author meant something other than what he wrote. What is written is absolutely no different than 3/1/3 or 3÷1÷3, no matter what LNCHBOX tries to tell you.
There are limitations in the syntax of rewriting this problem in line with a keyboard. To accurately rewrite the problem LNCHBOX posted, you would put 9 - 3 ÷ (1/3) + 1. That will get the desired result of 1 and is the same problem as the picture.
Writing 9 - 3 ÷ 1/3 + 1 is a different problem altogether.

Nah, they're going to tell you what I've been trying to explain, that 9 - 3 ÷ 1/3 + 1 =/= 9 - 3 ÷ (1/3) + 1.

"The correct answer is found by grouping 1/3 with parentheses and following the order of operations, with division taking precedence.
9 – 3 ÷ (1/3) + 1"
Agree - from their own explanation, the problem is not written correctly.
If it was asked to solve as written above, the correct answer would be, of course, 1.
9 – 3 ÷ (1/3) + 1"

I'm somewhat of a math Savant, and I can tell you that you are correct; those are not the same, one has parentheses.

Conventional answer: 9
Trick you answer: 1
Unconventional answer (by treating ÷ as everything on left divided by everything on right): 4.5

Is it 1?
ETA: Yeah, it's a bullshite question - if you mix/match symbols for the same thing, then you either don't know what you're doing or you're actively attempting to frick people up.
I know, shouldn't matter, but "/" is not a traditional operator - it's a numerator/denominator line - subtle difference, but an important one IMHO.
9 - 3 ÷ 1/3 + 1 should read the same as 9 - 3 ÷ 0.3333 + 1, but they want ÷ and / to mean the same thing to trick you, and if they mean the same thing, then you have to do them in order.
But, since ÷ isn't even on standard keyboards, it is an interesting mental exercise - doesn't really test the person's math skills, because it's too clever by half.

The answer as the problem is written is 9.
The problem is an incorrect rewriting of this question:
which has an answer of 1.

For the record I have an engineering degree and got it in 2 seconds.

I haven't look through yet but my guess is 1.
