Thanks. I see that this is actually correct. Thanks again.

If they were Arab I would understand but in America we go from Left to right while multiplying and dividing if there are nothing in th equation to tell us otherwise. It could be churched up to help those that are noengeneering inclinded though.

(6/2)(1+2)=9 Same answer but this would be easier for them to read.

I don't like how the equation is presented, which may be causing the person you've debated with to not believe that it is nine. I can say not from what I learned in college-last math/science course I took was Veterinary Pharmacology- but way back in school, what the answer is. The answer is nine.

I’m a math professor, and my view is that although the standard convention, if applied precisely and rigorously, does give an unambiguous procedure to follow, nobody, and that includes professional mathematicians, would ever write a formula like this. This is mostly because, after about 3rd grade, none of us ever use the division symbol ever again.


Considering that the average American only has a 5th grade education, it's no wonder something like this could confuse people.

Your doctor guy thought like this:

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

Apparently. But It's nine.

Thank you so very much for breaking it down for me(bit dime)as i never did school so maths(if its not +,-,%)is not straight forward to me.
now i,ve read your post,i to am getting nine.

sometimes us newbies do need telling but not in a patronizing way,a bit of respect didn,t hurt no one.
S+F for you op,another bit of knowlage for this awakening person,nice job

The only way I can get 1 with this is if I modify the equation like this:

6/[2(1+2)] =


But if the equation is left as:

6/2(1+2) =

I get 9.

He could have arrived at "1" another way.
The algebra which I remember, says that you do the actions within parenthesis first. So..

6 divided by the result of whatever 2 times the amount which is within the parenthesis

6/2(1+2)
=6/2(3) "6 divided by the total result of the equation 2 times3"
=6/6
=1


EDIT: uhhhh....I don't even know how I got sucked into this thread as I notice it is at least two weeks old, lol. So, I am just going to slowly walk away now.

Explanation: Use Algebra...

6/2(1+2)=?

We all agree that we do BRACKETS 1st ok... [I was taught bodmas]

6/2(3)=?

Now lets go algebra on this and say that a=3

Rewritten ...

6/2(a) =?

Remove the brackets ....

6/2a=?

If a = 3 the answer MUST be 1

Because must resolve 2a 1st...

6/(2a) =?

6/(6) =?

6/6 =1

Personal Disclosure: My Dad was a statistician... for him 1 + 1 = 3 ...for large values of 1


SaberTruth's post on page 1 explains that in simplified technical terms!

Because as long as there are still brackets you must resolve them 1st regardless. Ask any maths teacher!

Oi....

Please Excuse My Dear Aunt Sally

or

Parentheses, Exponent, Multiplication, Division, Addition, Subtraction....... That is the order in which you do equations....

6/2(1+2)=9

In kiddie terms...

1+2 = 3

so it's 6/2(3) or Six Secondths times Three

6/2 = 3... Yes because 6/2 is 6 divided by two......

so it's

3(3)=9

3 times 3 equals 9



I cannot beleive such a simple equation needed an entire thread to itself... Can we try a harder one now?

The problem with all these stupid math problems is notation used on a computer.

Are you saying 6/2(1+2) is:

6
----
2(1+2)

OR

6
-- (1+2)
2


In real world notation...you would never use "/" to show what you wanted.

It's not a problem with order of operations...it is a problem with notation. One way you get an answer of "1"...the other you get "9".


Or just put it into words...are you trying to say:

- Six divided by the product of Two Multiplied by the Sum of One plus Two

OR

- Six divided by Two Multiplied by the Sum of One plus Two.



Be clear in your question...and I'll be clear in the answer.

Explantion: Here is where you stopped using PEDMAS... there are still brackets/parentheses and yet your post goes on to start division!
WTFH???
The (3) is still unresolved!

Personal Disclosure: If you don't follow the exact protocol all the time its not maths its fanatsy!


The rest of this is FANTASY according to the standard being used!


6/2 = 3... Yes because 6/2 is 6 divided by two......

so it's

3(3)=9

3 times 3 equals 9

The problem is with how it's depicted on a computer. You can't really properly express "6/2" as it would look on a mathematics test. If I saw

6
- (1+2) = 9
2

Much easier to look at it like that.

HOW IS THIS TOPIC STILL IN DISCUSSION!?!?!?!

Jesus, it's proven by simple operations you were taught in grade school.

Just makes me cringe on the thought that people can't use simple rules. Makes me feel uneasy about our future.

when you added those brackets 6/(2a) you changed the whole equation. When you removed the brackets the equation was like this 6/2a= 6/2*a, which means if you go by the order of the operations it's nine.

Writing the equation fully in brackets = (6)/(2)((1)+(2))

Quoting:

The standard order of operations, or precedence, is expressed here:

terms inside parentheses or brackets

exponents and roots

multiplication and division (As they appear left to right)

addition and subtraction (As they appear left to right)

An expression like 1/2x is interpreted as 1/(2x) by TI-82, but as (1/2)x by TI-83. While the first interpretation may be expected by some users, only the latter is in agreement with the standard rules stated above.
