How To Solve This Equation? 3/1(1+2) = x

you notice most shit talkers are Anonymous Cowards

You are confused about parentheses usage. You're answer of nine comes from seeing the equation as this 3/1x(1+2).
The answer is 1 because you solve the parenthesis as a whole. 1(1+2) is solved first before doing the rest of the multiplication and division.

What difference does it make?

They're smart enough to know better.

You failed.

Dear god, people. There are two expressions (3/1) and (1+2) and since there is no operator between the two, standard convention is to solve the expressions and multiply.

3/1 = 3
1+2 = 3

(3)(3) = 9

Think of it like this: a(b) = x

Where a is equal to 3/1 and b is equal to 1+ 2.

(idiot)s

3/1(1+2)=x
1(1+2)=3x
3=3x
3/3=x
1=x

Give me something harder!

Google parentheses usage in mathematics.
Correct answer is 1.

Jesus, Lucifer & Muhammad: numeric totals of their names are the same


Best Viewed on you tube because of the annotations

Jesus Christ, Lucifer & Muhammad the mathematical mystery. Using one numeric alphabet the name Jesus, Lucifer and Muhammad have a same exact numeric total for the addition of their letters of their names. So what does that mean, watch the video to learn more.

Call me any name you chose, the answer will still be 1.

OMFG they are still arguing 1. lets give them a real equation
n2-3n+4/2 LMAO Oh wait I bet the answer is 1 all answers are 1 in GLP world

Here ya go...




maybe that'll knock some sense into ya.

Yes, the both rule. I understand how it works. HOWEVER, that only applies after you divide the 1 into 3.

besides of the colors, which tell us how the equation should be read, it is all a matter of interpretation actually... thats why the fights over this equation, or better, the two equations... because as someone posted before, this is simply a poorly written equation... maybe becauseof things like this, we have uncertaincies in universe, maybe someone forgot some brackets... :D

so the problem is, what we recognize as a term...

it seems like half of people see it like this:
3/1*(1+2)
other half like this:
3/(1*(1+2))

same with calculators, its all about interpretation of brackets... it should be even in the manual, how brackets are interpreted, because manufacturers know about these problems...

mathematically both are kind of correct...

3/1*(1+2)=9 is correct

however, brackets can also be solved like this:

3/(1*1+1*2)=1 which is correct too

no? :P

:| wtf is wrong with you people?

x = 9... simple as that.

Let me break this down into baby steps for you because I have to apparently hold your hand. Anyone that wants to reference this reply, go ahead. Remember PEDMAS as the order of operations. What that means is what we need to work out first...

1. Parentheses (what is inside them)
2. Exponents
3. Division OR Multiplication (which ever comes first left to right)
4. Addition OR Subtraction (Which ever comes first left to right)

Our problem is: 3/1(1+2) = x

Step 1. First we need to work out the problem in parenthesis. we keep the parentheses around 3 to represent the multiplicative relationship between 3 and 1.

3/1(1+2) = x --> 3/1(3) = x (or it could have been 3/1 x 3 = X)

Step 2. Move onto #2 in the order of operations.

3/1(3) = x --> 3(3) = x

Step 3. Now all we have left is a simple multiplication between the two 3's. This could have read as 3 x 3 = X.

3(3) = x --> 9 = X OR X = 9

The answer is 9.

Even this calculator here, a scientific calculator, states that is the correct answer:

Anyone else who refutes this has some education to catch up on.



Where do I think the problem lies in peoples responses?

It lies in the fact that people are mixing up Parenthetic importance around the three with a multiplicative relationship between the 3 and the 1. The parentheses only stay because they provide that multiplicative relationship. We could have also written it as 3/1 x 3 = X where the little x is the symbol for multiplication. We don't need to have that extra sign though when we have an existing parentheses around the 3 as it doubles as a multiplicative relationship for the 1.

9

why do people here find it so difficult to do remedial math?

First off, they are parentheses. Secondly, Math is very clear and precise on how it handles the breakdown of equations. Their is no "interpretation" of a math problem unless it has no clear answer (x = y). The problem lies in the fact that people are leaving the parentheses around the 3 and attempting to give it primary order of operation status. This is false. The only reason we keep the parentheses around the 3 is because we have a multiplicative relationship with the 1 next to it. We could have also written it as: 3/1 x 3 = X. We keep the parentheses because it provides that multiplicative (multiplication) relationship between the two without needing an additional sign.

why does anyone after a thought of 15 seconds think 1. damn 9 is the answer so fucking easy

Smartest thing you've said all day.

Because no one wants to admit their wrong or they are just THAT stupid.

If we follow some basic logic its 1 for sure.

BTW as I told before, scientific calculators do the job well and you can verify yourself if you have one, the other ones not.

However there must be a mess in a certain models some years ago, probably they messed up with some chips with other ones in some models:

a/b(c+d)=a/(bc+bd)

3/1(1+2)=3/(1*1+1*2)=3/(1+2)=3/3=1

a/b(c+d)=a/b*(c+d)

3/1(1+2)=3/1*3=9

ok... now look at the model of each of the texas instruments posted.

TI-85 and TI-86

TI-86 is the newer model

see the answer?

You just proved yourself wrong. Thanks for sharing.

It's a fraction times a whole number

3/1 * (1+2) = X

3/1is how we do fraction with a keyboard.

3/1(3)=x


you put a 1 under the whole number to make it a fraction
ex.3/1 * 3
to multiply you would turn your 3 into a fraction as so
3/1* 3/1 = x
then you would multiply the two fractions
3/1 * 3/1 = (3 x 3 = 9 and 1 x 1=1) = 9/1


X= 9/1

So all you 9's and ones were 50% right.

You all looked at it like a divide when in fact 3/1 is a fraction.

As you can see folks, I'm genuine, I did not lie on the operation with casio stuff on previous page. BTW some child (or dumb sheep)here, are still playing 'I'm going to take my ball and go home!' if its not 9.




Period

So you admit that the newer scientific calculator which you linked a picture to is right? and by that I mean you were wrong?

X= 9/1

Fraction times a whole number WTF!!!!!!


I got it right

IT's 9/1

GLP is full of retards.

A couple posts up and you can see the equation and how it's solved.

PACIFIST!!!!

OP the next time you try to put a equation online make sure you now what 3/1 really means, it's not 3 divide by1 the / makes the 3/1 a fraction making the entire equation a FRACTION TIMES A WHOLE NUMBER WHICH MEAN X= 9/1 A FRACTION
