It's 9

>>12072575
(9-1+1) = (10 - 1) = 9

nice except you're retarded

>>12072594
You are retarded
>>12072590
It's 9 you fucking idiot

>>12072573
19
>9-3=6
>6÷1/3=18
>18+1=19

>>12072596
In what fucking universe is 3÷(1/3)=1 you absolute chud level dumbass moron

I don't get it. Is this a 7 year old trying to get us to do their homework, or what?

>>12072573
1

>>12072625
You feel smart don't ya?

1

>>12072573
It's 9. Everyone who says 1 is a fucking idiot.

>>12072573
9-(3/(1/3))+1=1

>>12072664
9-(3/1)/3+1=9

>>12072573
it should be
9 - (3/(1/3)) + 1 = (9 - 9 + 1) = 1

Right?

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

>>12072673

This is why the school system is trash, they teach us this shit but not how to file for insurance claims or do our taxes

>>12072573

>>12072575
Correct.

You have to go back.

nice bait faggot

i'll be honest, anyone whose answers wasnt 9 is losing his time here.
just learn some math, get science litterate, then come back (there is a nice /sci wiki with decent recommendation),

i mean 1

>>12072573
[math]9-\frac{3}{\frac{1}{3}}+1=9-\frac{3}{1-3}+1=9-3-(1-3)+1=9-3-1+3+1=9[/math]

Go back to /lgbt/

>>12072810
how in hell 1/3 turns to 1-3 in your equation?

>>12072912
I simply rotated the fraction 90° counter clockwise from the anchor point in the middle also known as fraction bar/vinculum, what's the issue?

>>12072573
No because it's ambiguous without parenthesis.

>>12072939
What a fucking retard, math operators are all defined in such a way that there's never any ambiguity.

>>12072573
Only retards use the division sign

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

god this board is easy to troll, got me to reply sage goes in every field etc etc

>>12072664
>9-(3/(1/3))+1=1

>>12072672
>9-(3/1)/3+1=9

Nope. It is:

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

9-(1+1)

9-2=7

The operative order is

https://en.wikipedia.org/wiki/Order_of_operations#Definition

>The order of operations, which is used throughout mathematics, science, technology and many computer programming languages, is expressed here:[1][4][5]

> 1. exponentiation and root extraction
> 2. multiplication and division
> 3. addition and subtraction

>This means that if, in a mathematical expression, a subexpression appears between two operators, the operator that is higher in the above list should be applied first.

And if it's on the same level of order, the ones that are increasing the result should be done first. 10+3-5 can only produce one result. But it's easier to do 13-5 than 10+(-2).

9-3÷(1/3)+1
=9-9+1
=1

>>12072573
With or without a scientific calculator?

>>12072573
7?

>>12072573

>>12072683
but what's your answer?

>>12072573
7

>>12072958 is right

nevertheless the question is not ambiguous and the answer is 1

>>12074049
What’s wrong with division sign?

>>12072575
You always begin with the inner ones, so is 1

Using infix notation for non-associative operations is deprecated.

>>12072621
the one where niggers are considered equal

You know, this bait doesn't work without variables you know
There is no point of contention with just numbers

>>12073137
Isn't it PEMDAS tho so you add the 1 first then it's -1

>>12072573
The answer is 69, like always.

>>12074537
subtraction and addition have the same precedence

>>12072576
>>12072810
>>12072974

3 / (1/3) = 3 * 3

>>12072945
No it's not you faggot. No sane mathematician would ever write an expression like this.

>>12072573
Why did i get 21

>>12074717
Now i got 2.14
T. Brainlet

>>12074708
While I'm not arguing that it's sane to use the division sign outside of elementary school, I can't think of any operators that are defined ambiguously. Care to give an example?

>>12074749
Here's the associative property without parthethesis.

abc = abc

Here's the associative property with parenthesis

a(bc) = (ab)c

Notice something?

>>12074767
>Notice something?
No, I don't, am I retarded?

>>12074537
Communitive property of addition/subtraction.

>>12074767
Does that mean:
3 divided by 1/3 and then 9+1?

>>12074767
what the fuck is your point

>>12072573
yikes! this thread has a lot of retarded answers. use the lobachevksy (new style, 1961) method.

9-3/(1/3)+1=?
9-3/1.333=?
2.25

>>12072573
This is a sad day for /sci/, defeated by a simple and unambiguous equation where there's not even really any trick to it.

you guys are just joking, r-right /sci/?

>>12072596

bedmas,

Bedmas,
no brackets,

bEdmas,
no exponents,

beDmas,
there is division.
3/(1/3) = 9
equation is now 9 - 9 +1 =

bedMas,
no multiplication

bedmAs,
there is addition
9 + 1 - 9 = 10 - 9

badmaS
there is subtraction
10 - 9 = 1

the answer is 1
CONGRATS! YOU FAILED PRIMARY SCHOOL! HURAYYYYY!!!

>>12074767
yea they are the same and you said lots of words without making any point

3/(1/3) would give 9, so it's just 1

>>12072573
The answer is 1. Anyone that says otherwise needs to return to 5th grade.

I worry about humanity...

>>12072573
What is wrong with sci...
3/(1/3) = 3/0.33333... = 9
9-9+1 = 1

Very funny, nice troll /sci/.

For a science and math board you guys sure are dumb.

>>12072573
Uno.

>>12072575
3

>>12072573
No

Holy shit, there are a lot of retards in this thread.

>>12072573
>>12072597
The only right answer

>>12072573
1+1/3 = 1 (sigfigs)
3/1 = 3
9-3 = 6
6

it's unsolvable... this is one of the lesser-known millennium prize problems

>>12072573
Nice bait OP, but does no one know their order of operations?

[eqn]9-3\div\frac{1}{3}+1[/eqn]
[eqn]9-1+1[/eqn]
[eqn]9-2[/eqn]
[eqn]7[/eqn]

>>12075760
Wrong. When dividing with a fraction you must turn the whole number into a fraction as well.

3 / (1/3) becomes (3/1) / (1/3)

This can be simplified by following the "keep, change, flip rule" which would make...

3 * 3

= 9

>>12072573

9-(3/(1/3))+1
= 9-3x3+1
=9-9+1
=1

Why does everyone think it’s 9? Is this the result of mutt education?

>>12075760
This has to be bait...
