It's 1.

9 - 3/(1/3) + 1
= 9 + (-1)(3)(3/1) + 1
= 9 + (-1)(9) + 1
= 9 - 9 + 1
= 0 + 1
= 1

>9 minus 3
6
>6 minus with dots (1/3)
5/3
>5/3 plus 1
6/3 equals 2
The answer is 2

isnt it kinda weird how 9-9+1 equals to 1 ? i dont know why but i think they taught me you could do the addition first or whatever you like. so instead of 1 the answer is -1 (if i do the addition first)

>>36325298
I love how he got so embarrassed that he deleted his post on an anonymous imageboard. You fucked him up, anon.

>>36325390
for example 5+6-2

if you do addition first , the answer is 9. but if you do subtraction first, it's still 9. what the hell is happening

>>36325435
You're an idiot. You only need a common denominator for adding fractions, not multiplying them. Not that it matters. Consider:

>3/1 = 9/3
>9/3 / 1/3 = 9/3 * 3/1
>= 27/3
>= 9
>9-9+1 = 1

>>36325390
You CAN add first, but then you get -9+1=-8. 9-8=1. Same result.

Why is /r9k/ so fucking stupid?

>>36325562
no, you still need them.

Original

>>36325390
>>36325426
subtracting is essentially adding a negative number.
adding numbers can be done in any order and the answer won't change.
9 - 9 + 1 is actually 9 + (-9) + 1
do the left addition first and you get 0 + 1 = 1
do the right addition first you get 9 + (-8) = 1
you do NOT get 9 + (-10)

>>36325604
Nice excuse.
>>36325613
How can you be so unfathomably stupid? -9+1 isn't -10, dumbass. It's -8, you fuck.

i get it now anon. thanks for clearing that up. stupid HS teachers

Once you work with polynomials and algebra a lot, the order of operations becomes second nature.

You look at that equation and see three distinct terms.

nine
-3 divided by the inverse of 3 (so -3 times 3)
and one

Then you just add them together

>>36325883
>Once you work with polynomials and algebra a lot
aka once you take math at the high school level

>>36325915
Makes me wonder how many of these so-called """robots""" are just underaged fucks.

I got -9

>>36325163
It depends on the order you do it in which is entirely subjective because it has no fucking brackets. That's why this always causes arguments.

9-3=6
.3 recurring+1=1.333333...
6 divided by 2.333....=4.6 approx

if you do above but using fractions instead of decimals you get 4.5

If you use a different order of operations, you can also get 1 as the answer. Basically, there are an array of possible answers depending on how you tackle the question, making this so baity.

>>36325163
hey easy this is 9-3=6:3=2+1=3
Answaer is 3 faggots !!!!!!!

It's 68, isn't it?

>>36326058
You're a dumbass. There's only one order of precedence in here, brackets or not.

Multiplication and division always happen before addition and subtraction. No exceptions. The answer is always 1.

>>36326058
There's one correct way of doing it. What you're saying is, if you did it in a retarded way you'd get a retarded answer. Fascinating

>>36326058
>The order is subjective
No it isn't you cock gobbling retard.
You can't just slap brackets into an equation any way you feel like it.

>>36326068
bait
>>36326106
Nope, different cultures and countries sometimes use different orders of operations, don't assume everything is the same as America. This problem caused a massive storm in Japan as schools are not as federally managed there so different people would solve it in a different order.

Explain.

>>36325163
Negative 1.

this >>36326225 is why >>36325562 heard they want to 'get rid of order of operations'.

What they mean is that people take BEDMAS too literal because schools only teach the mnemonic and dont bother explaining shit like >>36325651

>>36326225
>Hell you can even get -1 as the answer using BEDMAS.

yeah, you can get a wrong answer if you do it wrong. You're repeating yourself.

>>36326225
>but if the brackets are not provided, what can you do but fall back on the ordering that you were taught in school?

If there are no brackets, it's because they're not needed.

>There are different orders.

No there aren't. If you put brackets in a certain way that gives you a different answer, then it's another problem entirely.

>>36326282
BEDMAS. So we're using Division, then Addition, then Subtraction

9 - 3 / 1/3 + 1 =

3 / 1/3 = 9

9 + 1 = 10

9 - 10 = -1

>>36325163
+ - 9 * 3 / 1 3 1 = 9

9 - (3/(1/3)) + 1 = X
9 - (3*(3/1)) + 1 = X
9 - 9 + 1 = X
1 = X

>>36326158
Ever heard of PEMDAS and BODMAS? Different schools of thought. Both are equally correct. Just because you Americans only get taught one thing in your rotting schools doesn't mean there are not multiple ways to tackle a problem.

>>36326282
By doing the addition before the subtraction, see >>36326375

>>36326337
Yes there fucking are. Maths papers in the UK specifically say what order to use if no brackets are provided because they test the students ability to do different order systems.

>>36326396
No the picture is + - 9 * 9 / / 1 3 1 = 1 in Polish notation

>>36326375
Oh for fuck's sake, when will this meme die

Divisions don't have to come before Multiplications, or Additions before Substractions. The correct way is to do it from left to right.

holy fuck you guys are dumb lol

>>36326375
>>36326411
I can't tell if you're baiting or if you're really this retarded.

It's not 9 + 1, you utter imbecile. It's -9+1, or -8.

And keep in mind that it's not "addition before subtraction," either. Addition and subtraction have equal order of precedence. When both are present, do it left to right.

>>36326058
>which is entirely subjective

Wrong, the order of operations is an objective fact of maths. Parentheses come first, exponents, then multiplication or division depending on which comes first left to right, then addition or subtraction depending on which one comes first.

The answer is 7.

>>36325163
The problem comes from whether the 1/3 has implied brackets or not.

I'm an engineer, and if I ever saw this, I would presume implied brackets, but some fag will come on here and go "hurr hurr, you're wrong, there's no implied brackets", which I assume is the whole "trick" to this trick question.

Didn't read the thread btw.

>>36326449
Jesus Christ someone get it right
+ - 9 / 3 / 1 3 1 = 1

Well I mean its technically 0.9090909090 (etc.) or 0.9999 (etc. with a 1 at the end) depending on whether you did 0.33 for the 1/3 or 0.333333 (etc.) for the 1/3.

>>36325163
3:1/3 is the same as 3/1:1/3, which in turn is the same as 3/1x3/1. you get 9-9/1+1 which is one
that's how i was taught at least, though i did think it was 9 at first.

>>36326669
Come to think of it, by no notation known to man would that 1/3 ever not be considered a flat out bracketed fraction. In which case, I have no idea why this problem was posted. The "trick" then is just to divide -3 by 1/3, which makes it -9, before performing addition and subtraction

>>36325163
Are you all shit posting because I'm pretty sure it's 9, because 3/.3333~ is 1, 9-1 is 8 and 8+1 is 9.

9-3/(1/3)+1

Ok you fags time to use math for once.

3/ .333 repeating equals 9. 9-9 is 0. 0 plus 1 is one. The Answer is one, and first post is right. So study and stop thinking y'all are smart.

>>36325163
*scrolls next post*

9 - 3 / (1/3) + 1
SO
3 / (1/3) = 9
then
9-9 = 0
then
0 + 1 = 1

The answer is 1 brainlets

>>36325163
9-3= 6
6/1= 6
6/3 = 2
2+1= 3

Ergo, the answer is 3.

>>36325163

>Subtraction
9 - 8 = 1


>>36328936
What the fuck

>>36328943
You did it backwords you dumb fuck

You take away 3 from 9, that's 6

THEN 6 wholes divided by 1 over 3 equals 18 wholes.

18 wholes plus one equals 19.

You guys are fucking retarded. PEMDAS (parenthesis,exponents, multiplication,division,addition,subtraction)
The first one to do is division. When you divide by a fraction its the same as multiplying.
3x3=9
After division is addition. 9+1=10
Now all thats left is the subtraction
9-10=-1

>You don't disregard one of the answers just because it's the same as another.

In this case, yes you do. If two of the 4 answers are "25%", then the chance becomes 50%, which is B, but picking B would mean you have a 25% chance of being right. Picking C doesn't make sense either

There is no answer

>>36325390
There is technically no such thing as subtraction. It's just adding a negative number.

9 + (-9) + 1

Anyway, your'e saying that -9 + 1 is -10, which is retarded.

3/ 0.33=9
9-9+1=1
Answer is 1

You multiply/divide before adding numbers together...

9 - 3 x 3/1 + 1
9 - 3 x 3 + 1
9 - 9 + 1
9 - 8
