6÷2(1+2)
= 6/2(3) <- at this stage the parenthesis represent multiplication, not order of ops
= 3(3)
= 9

why is this thread just south of 140 pages??

Re: Math: 6÷2(1+2) = ?
does your word change the laws of math?
Quoting: Anonymous Coward 32614604

I have been quoting the laws of math since the beginning !! Nothing I said was from my ass! I am simply quoting math laws, principles, notation, etc...

ONE MORE TIME:
a ÷ a = 1
Any variable with no coefficient, has a 1.
THEREFORE:
a ÷ a = a ÷ 1a = 1
a ÷ a = a ÷ (1a) = 1

Fractional Coefficients REQUIRE ( ) if they use a SLASH instead of a horizontal line, EG:
(6/2)n = 3n
6/2n = 3/n for the same reason that a/1a = 1

(6/2)(2+1) = 9
6/2(2+1) = 1

6(2+1)/2 = 9
6/(2+1)2 = 1

Here is how an OBELUS works:

Obelus: The obelus is primarily used as a symbol for division
Slash: Used between numbers slash means division, and in this sense the symbol may be read aloud as "over".
Solidus: The solidus is a punctuation mark used to indicate fractions.
Now, the obelus and slash can be used interchangeably as long as the slash is interpreted as division NOT mistaken for a solidus.

Here is a real world example of the equation at hand:
"I'm trying to free your mind, Neo. But I can only show you the door. You're the one that has to walk through it."

Re: Math: 6÷2(1+2) = ?
A pair, is 2. A pair of anything, is 2 of them. Yes, it can be evaluated as 2 * x, but the value must remain so the meaning is different.
Situation: You have apples to divide among people. You have 6 apples. A family (f) is 2 adults and 1 child, so f = 2+1

6 apples divided by a pair of families (where there are 3 in a family). f is a family of 3, so f = 3
6 ÷ 2f = 6 ÷ 2(3) = 1
6 ÷ 2(2+1) = 1

If you can do this question correctly, then you should get 1 for the original equation.
If you get it wrong, that is why you get 9.

12x²y÷4x+(6x – x)²

Re: Math: 6÷2(1+2) = ?
i went through it again and i actually now come up with 1.

Order of operations:

Brackets
Exponents
Division
Multiplication
Subtraction

6÷2(1+2) =

= 6÷2(3)

= 3(3)

= 1

i respectfully retract my previous answer of 9 i was doing M before D

Going left to right is part of the order of operations.
Quoting: Anonymous Coward 32614604

Technically no, but it gives young students a sense of order. Adding and multiplying is associative, so it doesn't matter what order you them in. Subtracting and division are the same as adding and multiplying. It is knowing things like this, as well as other details of maths, that allow you to see that this equation is solved as 1.

It is important to note that this stipulation about \from left to right"is entirely extraneous, because the associative laws of addition and multiplication ensure that it makes no di erence whatsoever in what order the additions or multiplications are carried out.

Quoting: caper_26

if it makes no difference whatsoever in what order the operations are carried out, then WHY are some people saying "1" and some people saying "9"?
Quoting: Anonymous Coward 32614604

The order of operations matter. What doesn't matter is working left from right. Say you have worked out the multiplication already, now you are left with a bunch of addition and subtraction, it doesn't matter what order you do it in, the answer will be the same. Hence, working left to right is not part of any rules in mathematics.

Although, yes, we do teach kids to do math from left to right. That is why so many of us thought it was a rule.

But the fact is, that doesn't even matter in this problem, because it never should. Even if you work the problem left to right, you still get the answer as 1.

And I used to seriously, firmly, and adamantly believe the answer was 9.

Re: Math: 6÷2(1+2) = ?
no they don't, / is the same as divide symbol. so for mutiply and divide, you go left to right.

6/2 * (1+2)

could be written as:

a * b

where:

a = 6/2
b = (1+2)

the bizarre bit is that some people would rather write it as a/b for some reason. it is clearly multiplication, not division.
Quoting: Anonymous Coward 32614604

I bolded your equation above. It is = 9.

6 ÷ 2n = 3/n
6 ÷ 2 * n = 3n

If you don't understand this, say so. Don't say it isn't, because your word doesn't change the laws of math.
Quoting: caper_26

Yea I don't understand "6 ÷ 2 * n = 3n"

The only way I figure that to equal 3n is if it is this (6 ÷ 2) * n = 3n

The input is wrong. The (1+2) belongs in the divisor/denominator. That is where the obelus puts it.

Pretty sure multiplication and division are of equal value and it doesn't matter which you do first... but I have been wrong before so I could be wrong here.

Doing multiplication first probably does serve you well though or else you could end up in a bind like with this problem if you treat obelusi and divisional slashes as a solidus like I was doing here....

It really shouldn't matter if you do the problem correctly. But yes, here multiplication before division will net you the right answer.

Re: Math: 6÷2(1+2) = ?
the input in wolfram alpha is wrong.

the input I saw used a solidus. However, I used a high powered calculator on an electrical engineering website and that also calculated it wrong.

n(n) simply means that the whole stuff is part of it and you need to solve it first.

I was actually unable to verify that the distributive property would require you to distribute before any other multiplication or division is done so I am not sure you are correct there...
