Math: 6÷2(1+2) = ?

6/2(1+2)=9 but that is not what op wrote. :D

^^READ THIS AND LEARN PEOPLE. THE ANSWER IS 9 ALL YOU DUMB FUCKING INBREDS AND THIRD WORLD COUNTRY RETARDS.

Another fine example of superior American reasoning.
You fail to spot op´s subtlety.

1+2 = 3 (parenthesised)
6/2 = 3

3x3 = (division account outside the parenthesised multiplies the remainding parenthesised)

nine

yay for math


oops.. reiterating... now, if only we knew how to run a safe reactor....

The order of operations is the order in which all algebraic expressions should be simplified. Oftentimes, the meaning of a complex expression changes depending upon the order in which it is calculated. The order of operations is:
Parentheses
Exponents (and Roots)
Multiplication & Division
Addition & Subtraction
This means that expressions within parentheses are evaluated first, then exponents (including roots, i.e. radicals), then multiplication and division (at the same level), and finally addition and subtraction (at the same level). If there are multiple operations at the same level on the order of operations, move from left to right.Whichever mnemonic you use, be aware that multiplication does not always come before division
1) 1+2=3
2) 6:2=3
3) 3x3=9
6 ÷ 2 (1 +2) = 9

Do you think that you are so well educated when solving math-problems that are teached at the age of 10?

its 1.... you start with the parentesis always!!
Whatver is in the parentesis, u start from right to left.

Where's Chinas answer to this? I'm going with whatever China says. The answer is 1 though.

stupids, its easy 1

1 is the answer.... 1!!

Mmmmmm....
There are 6 cakes

2 mothers each have 1 son and 2 daughters

How many cakes for each kid?

6 cakes / 2 mums (1 son + daughters)
6 cakes / 2 mums (3 kids)
6 cakes / 6 kids
1 cake / kid

What people forget is PEMDAS needs to be applied Left to right.

Rules

1. Calculations must be done from left to right.

2. Calculations in brackets (parenthesis) are done first. When you have more than one set of brackets, do the inner brackets first.

3. Exponents (or radicals) must be done next.

4. Multiply and divide in the order the operations occur.

5. Add and subtract in the order the operations occur.


So 6÷2(1+2) = ?

First in order is (1+2) which equals 3
so now you have
6÷2*3=?
Now remember it is done from left to right so even though in PEMDAS multiplications comes first... in the problem at had starting at the 6 and working left to right the division comes first so then you divide 6÷2=3
So now you have 3*3 which equals 9.

So 9 is the correct answer and if you come up with 1 as an answer you need to remember it is left to right

You all fail:

Law of distribution, you need to know more then basic pemdas to do anything in life yo's...

whenever you have multiplication of terms being added you must multiply each term by the multiplicand,

i.e. 2(1+2) = (2*1 + 2*2) = (2+4) = 6

so

6/2(1+2)
6/(2*1 + 2*2)
6/(2 + 4)
6/6
1

IT'S 1

LOL It took 95 pages to come up with the answer 1?

6/2(1+2)
6/2*3
6/6
1

...

6/2(1+2)
6/2*3
6/6
1

Is wrong.


6/2(1+2)
6/2*3
3*3
9

Is right.

Are you retarded?

You all fail:

[link to en.wikipedia.org]

Again, Law of distribution, 2(1+2) is a combined unit, and must be simplified 1st.

is it 12?

Forgive me if someone wrote it already but....
Please Excuse My Dear Aunt Sally. Parenthesis, Exponents, Multiply, Divide, Add, Subtract.

6÷2(1+2)
6÷2(3)
6÷6=1

Before calling me retarded, you should realize that what you are saying has nothing to do with the calculation.

2(1+2) is not a unit. It should read 6 / 2 x (1 + 2)

I did a bit of googling around and 9 is the correct answer to this problem, so looks like I'm not that retarded after all.

But you are assuming it's a mathematical distribution problem, giving a potentially a wrong answer. The answer is conditional upon operator precedence rules applied - and without explicit operator precedence specification, then the result is ambiguous and non-deterministic.

What is this "math" you speak of, stranger?

The answer is both 9 and 1

Thank you, thank you very much!

(Elvis has left the building)

There can't be 2 answers to 1 equation.

There can be if the question is ambiguous to begin with.

HA! HA! HA! HA! HA! HA! HA!

solve this equation for x:

x = square_root(4)


there are TWO ANSWERS!!!!!11

This is like arguing the truth value of a question with little circumstance. As I read through the posts it is clear that math inhibits our ability to act humane. Some of us are taught one or two rules differently than others, or our memories serve us better...anyways...the matter of a correct answer is not relevant, this is 2012 if you get upset over people getting math problems wrong on a conspiracy forum...you might be a bit neurotic. Take some xanax and stfu.

HA ok, you got me! Positive and negative. :)

6÷2(1+2) PEMDAS
1st 1+2=3 as in 6/2 (1+2)
2nd 2*3=6 as in 6/2*3
3rd 6/6=1 as in mother fucking one. How did this go 90 pages?
1 goddammit now everyone shut the fuck up.
What is 2+3*(0-2(6-5))?
