Dividing by a fraction is the same as multiplying by it's reciprocal so dividing by 1/3 is the same as multiplying by 3. Now you have x - x + y. PEMDAS is P E (MD) (AS). Addition doesn't take precedence over subtraction, you move from left to right. Here's what [link=(Cymath)]https://www.cymath.com/answer?q=9%20%E2%80%93%203%20%23%201%2F3%20%2B%201[/link] has to say about this...lo and behold they come up with the same answer.
I love when people downvote things or reply "ugh" when they're just wrong. Though I guess now cymath will be considered "fake news" since it clashes with your beliefs.

I saw that this morning. They say the answer is 1, but they are dumb and think that because they put spaces in certain places, that pemdas changes and you don't go left to right.
And none of this changes the fact that the problem is stupidly written.
The answer is 9.
3÷1 =3
3/3 =1
9-1+1=9
wtf are you smoking? Can I please have some?
(9)-(3)/(1/3)+(1)

My issue from hat thread is that i still was interpreting as the original way that OP wrote it I will always say that this one is ambiguous.
You're good at your job.

You can't just randomly decided when you want to divide by fractions and shite.
3 ÷ 1/3 is the EXACT SAME as 3 / 1 / 3, based on order of operations. You do the division left to right. If you want 3 ÷ 1/3 to equal 9, you should write it as 3 ÷ (1/3) or 3/(1/3).

The equation looks bllue to me.

That's the problem, both this written out OP and the one from a few months ago incorrectly interpret the problem shown in the image.
Exactly. I've been arguing this for 10 pages.
9 - 3 ÷ 1/3 + 1 =/= 9 - 3 ÷ (1/3) + 1

It is 9...

but it's written as 3 divided by 1/3. literally copy pasted the problem exactly as it's written in the title into cymath and it says 1.
the equation is stated as:
9 space - space 3 space 1/3 space + 1. Every digit is separated by a space implying 1/3. If we take it as 9-3/1/+1 then why would there not be spaces between the 1/3.

That's an outdated order of operations system on the TI-34. Type that into a TI-84 and tell me what it says.

That's not your dress. You found a picture on Google and put the equation in there!

Put this into that calculator: 9-3÷1÷3+1
Tell me what it says.

Look at the rules of math, you can not change a / to a horizontal line, they mean different things
However, cymath says frick the rules

Knowing what the OP was TRYING to write, yeah, I can see how you would think that.
If this was just some random question, those spaces are irrelevant. The OP is the incorrect way to transcribe the problem. The answer to the problem in the OP is 9. He was trying to get an answer of 1.

I'd say 9. You don't just assume shite in math. That's why it's the best subject. ÷ and / are the same operation. If you get 1 you are assuming that 1/3 is in parentheses.
It's 9-3/1/3+1. Divide first left to right. 9-1+1=9.
Really a dumb question though.

Answer is -1.09
1/3=.333333333
3/.3333333= 9.09
9.09+1= 10.09
9-10.09= -1.09
1/3=.333333333
3/.3333333= 9.09
9.09+1= 10.09
9-10.09= -1.09
