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

Ok I am back from church. I should have prayed for us 9 tards also. Last time.

New link

[link to www.mathgoodies.com]

The original problem one more time.

3/1(1+2) = x

Parentheses first.

3/1(3) As in we take from the original problem (1+2) and no that equals 3. So now we have 3/1*3.

Notice no more parentheses.

Now we do multiplication and division left to right. The first one on the right is division. So, lets do that first. 3/1=3. And for those with a science calculators: If Johnny had 3 apples and divided them amongst himself 1, how many apples does Johnny have.

Now the new problem after the division is now 3*3.

And what is 3*3.

Well after all it is a conspiracy site so it must be 1.

Is this thread going to go on to 130+ pages like the other one?

if you truly think it is 9, you are wrong. Yes multiplication and division get the same priority, but once thats all that is left, you MUST go left to right. therefore the correct answer is x=1.

3/1(1+2) = x
3/1(3)=x
*3 *3 <- Multiply by 3
1(3)=3x
3=3x
- - <-Divide by 3
3 3

1=x or x=1 is the correct solution.

GOD I hope so. The 1 tards still have to give a reasonable answer on why it's 1.

Parentheses first 1 tard.

what it comes down to is that some people interpret the expression as:

3/1*(1+2)

and some people interpret it as

3/1/(1+2)

obviously two things next to each other with no sign is a multiplication, not a division

gave 2 links that prove that. Give 1 link that says otherwise.

Not quite right, division has priority over multiplication, thus x=9 not 1.

no it doesn't

the only thing in parenthesis is a 3, now what would you like me to do with that 3? i already did what was in the parenthesis. Have any of you 9 tards ever heard of using parenthesis to separate numbers that are to be multiplied? hmmmm.... let me scratch your un-educated head for you.

No wonder my taxes went up. He must believe it's 1 also.

Exactly. It's a very poorly written equation and exploits a slight ambiguity in the order of operations. After parenthesis (brackets for you brits) and exponents (powers) it is then MULTIPLICATION and then division.

However, the ambiguity comes in that multiplication and division are seen as being "on the same level" and so those CAN be done left to right.

Real answer: both are right.

And some of you are REALLY some argumentative, know-it-all shitheads for thinking YOUR way, and ONLY YOUR WAY is the right one.

Just saying....

No, its a good one.



.

Multiplication and division have the same priority from left to right.

Using your logic, addition should be done before subtraction in an equation...

Now you blame the equation saying it's poorly written?

It's a math equation you dumb fuck. It doesn't have spelling or grammatical errors.

and another thing... MY way and ONLY my way is the right way. This isn't a fucking thesis on migrating birds. it's math. 1+1 =2. There's only one right answer.

Ha Ha LMAO those that think 1 is the answer will solve this equation x + 4 = x + 3 and convince themselves there actually is an answer.

There is no great import to the answer to this question.

Just pick a set of operator priorities, and a left to right or right to left or inside to outside execution priority, and use that when you pose the problem, as well as when you compute the solution.

All will be well.

Be happy.

OMG!!

At least the ones that have come out with a '1', are understandable..

FFS... You just opened up the retard floodgates with that one! That's another 200 page thread in and of itself.

Shhh, if you listen carefully, you can hear all the 1tards thinking out loud...



X = 1 !!!

1 = x

I agree with the German, the answer is 9 Order of operations or
BEDMAS for the dumbas

Brackets
Exponents
Division
Multiplication
Addition
Subtraction

You dipshits have to get rid of the parenthesis first by multiplying it out then divide or multiply next left to right.

It's 1, you stupid fucks.

Oh great, the result of an American Education :S

The 1 isn't inside the parenthesis you stupid fuck. Once you complete the equation inside the parenthesis, you work left to right doing the division then the multiplication.

It's not "parenthesis and everything around it" first.

Now drink some bleach and kindly remove yourself from the gene pool.

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

Being stupid just wasn't enough... You're a real go getter.

The reason for this is that when a web browser reads a HTML page with multiple spaces in a row, it displays that HTML as one space.

For example, these lines will probably look the same when you read the message, but if you quote this message, you can see that one line has more spaces than the other line:

x x

x x

Multiple spaces don't show up in HTML! You can't format things with spaces!

Here are those two lines again, but with each space replaced by a dot:

x........................................x

x.x

_____3_____
1(1+2)

does that make it easier?

Course I never made it past differential equations

Calmshock, while your answer is correct, your tact towards those that are confused seems to be lacking but I will help argue the point as well.

First we have the initial equation:

3/1(1+2) = x

We need to work out the items inside the parentheses. IMPORTANT! By doing this, we clear the item of the parentheses as it has been fully worked out into a single solution:

3/1 x 3 = x

Then we work division OR multiplication from left to right:

3 x 3 = x

Next finish the equation:

9 = x OR x = 9

It could also be written like this... 3/[1(1+2)].... THIS equation equals 1.
