Math: 6÷2(1+2) = ?

All fixed

yeeeeeeeeeeeeeeeeahhhhhhhhhhhhhhhhhh.............

9

It's 1 all day long. Order of operations. Multiplication come before the division. Parenthesis | Exponents | Multiplication | Division | Addition | Subtraction <<<Order of Operations

This is basic Algebra people. It's 1.

I have shown scientific calculator doing the problem and many other websites and programs doing the problem.

All getting 9.

Have you shown anything showing an answer of 1?

Everyone of these websites I typed the equation EXACTLY as the OP had it. Using ÷ not /,x or adding anything after the first 2.

Video here show me inputting exactly as OP put it.

I can show about 50+ more sites that all show this same thing.

Still 9. Multiplication DOES NOT come before Division.

Check my wolfram image. Input exactly as OP. Cant believe you let Casper's double talk change your mind. Especially after all the proof against 1.

Including your own variable work.

Every image I put in I used 6÷2(1+2)... exactly. I substituted nothing.

Video of me doing on scientific calculator. And image to prove it was "scientific".

:this^^^:


Funny because Syrius, the original poster is actually aruging there is a difference between...

6÷2(1+2) and 6÷2*(1+2)...

Which is the weakest argument for 1 in this whole thread. Saying he was showing the 2 up against the parenthesis as indication it was the "denominator". WTF!! Even though it would still be wrong, he would of at least put...

6/2(2+1).... I might of bought his story then. The answer would still be 9, but this thread is getting better and better.

OP didnt even know the answer.

Division is the inverse of multiplication. This is why the "left to right" rule is in place. To help people who cant see the inverse. We can get rid of "left to right" by making everything multiplication. See below



Which would make this equation.


6 * .5 * (2+1)... this should be really easy for anyone.

6*.5*3=9

Can re-arragne in any order.

.5*6*3=9

Can even distribute.
6 * .5 * (2+1)
6 (1+.5)
6*1.5
9
Anyone want to argue with this?


So instead of dividing by 2 multiple by .5!!!!!

6/1 ÷ 2/1*(2+1) = 6*.5*(2+1)

It would be nice if they looked at all aspects of math before solving. Nice COPY & PASTE from yahoo... On yahoo, I am a space physicist, didn't you know?

says the tard

Sure is.

Theses bozos can't even solve the following:
12x²y ÷ 4x + (6x – x)²


Nor can they solve
a ÷ 1a correctly

Nor write "six halves of n" properly

Thread: 6÷2(1+2)=? SOLVED by the Professor of Mathematics at California State University [video]

Thread: 6÷2(1+2) = 9 (Page 2)


Pretty overwhelming proof.

My last post to this thread. As other threads show more info/proof on the first post. Not jumbled up over 140 pages.

Good luck "space physicist".

Here is how an obelus works: [link to www.freeimagehosting.net]

Here is how grouping in algebra works: [link to cstl.syr.edu]

Here is a link for those who get 9: [link to i48.tinypic.com]

No wonder you can't evaluate this expression.

according to how they teach order of ops in Canada (BEDMAS) and that DM are equivalent in precedence, then left to right order is used. i still get 9.

from: [link to math.about.com]

"There are a couple of things to remember when applying the PEDMAS/BEDMAS order of operations. Brackets/Parenthesis always come first and exponents come second. When working with multiplication and division, you do whichever comes first as you work from left to right. If multiplication comes first, do it before dividing."

based on that its 9.

Except that (2+1) is in the denominator, since 2(2+1) is a single unit

consider 6 ÷ x²
x² is x(x) = x * x
So 6 ÷ x² = 6 ÷ x * x = 6 ?
No because x² = (x²)

Just like 2(2+1) = [2(2+1)], but as x², we don't need to use redundant parentheses. Some "special" people insist on using them though because they are easily confused.

i see your viewpoint but unless redundant parenthesis are put in then the answer is open to interpretation.

if it was 6÷(2(1+2)) = ?
then it would undeniably be 1.

9

6÷2(1+2) = 1
6÷(1+2)2 = 1

(6÷2)(1+2)= 9
6(1+2)÷ 2 = 9

For starters, I'm not arguing 6÷2(1+2) and 6÷2*(1+2).... Look at the post, a few pages back, that you replied to, genius.

I'm going to be blunt with you, pal. Your trolling attempts are weak and on the verge of annoying. And no, I'm not going to give you the pleasure of restating my arguments for the 7th or 8th time. There is no point.

Your oblivious mind will continue reading and interpreting my words wrong. As you have proven on at least two occasions. Personally, I can tell by your posts ALONE that you have a hard time coping with reality and continue repeating yourself with nothing new to add, the same recycled jargon. Let's be honest, what are you afraid of exactly? An empty existence, where in the light of others, you go out of your way to misquote them and pretend they are ignorant for your own sake?

Before you argue with someone, regardless of topic. Listen to their arguments instead of making shit up. It makes you look a dolt.

I really hope you find peace, and maybe some closure in your life. However, it won't be here so gtfo.

There is no troll attempts. Only showing math laws and principles to those who do not know about them

the infamous wolfram even knows how to simplify 6 ÷ 2n. However it does not know how to substitute variables with values.

Most people: "It is 9!!!" with no explanation besides "left to right" then they convert 2(2+1) to 2*(2+1) which is incorrect. 2n = (2*n)

Failure to know that the (2+1) is part of the divisor. Which means the multiplicative inverse of it, as well as the 2, must be interpreted.

I was quoting Forgotten, sir.

You are 1 of the few that has took the time to research all possibilities and seen the light.

How is any of that "trolling".


Definition: In Internet slang, a troll is someone who posts inflammatory,[1] extraneous, or off-topic messages in an online community, such as a forum, chat room, or blog, with the primary intent of provoking readers into an emotional response[2] or of otherwise disrupting normal on-topic discussion

Where have I done ANY of that ??? Actually, I can find SEVERAL other people trying to do the above, not me.

ok..

Apologies !! I was the last post, so I thought you were talking to me !!

Forgotten has banned me from his thread, because he doesn't want me converting anyone on his 9 bandwagon to 1. I am also on his "foe" list too. I find that rather amusing.
