Math: 6÷2(1+2) = ?

bottom line:


Is 1(n) = 1n ?

nine.. stop it..............

This is correct.

It is not 9. It is 1. You stop it.

You cannot separate the 2 from (2+1)

If you were to separate it the answer would be

6/2 × 2 +1 which would be 7 but the () are gone so

6/(2*2)+(2*1) which is 3.5.... wait that's not right either...

Where did you get the idea that you can separate the 2?

2(2+1) = (2+1)+(2+1) = 6

6/6 = 1

If you can explain to me how the 2 is magically separated then I will say 9.

The only way to rid the 2 is dividing the whole problem by 2

Which gives

3/(2+1) still equals 1

Why is this 131 pages it's basic algebra, parentheses first to simplify the equation. Answer is 1. [link to www.math.com]

They get 9 by doing the division first instead of clearing parentheses like you're supposed to.
6/2=3
3(2+1)
3*3=9 durp

Let's fast forward, will there ever be a conclusive answer that everyone agrees on?

I don't believe our egos are capable of coming together, ever...which is sad because the language of Mathematics was conceived to be universal, in the grander scheme.

Yet, here we are a year later... bickering. The same problem, the same results, some faces familiar... others have just joined the fray.

You must ask yourself... because things of this nature have driven good men insane. Perverse, and lost in their thoughts as if they were peddling the newest drug in the lobby. We should resume this discussion with honorable mentions to all the greats.

I salute you Pythagoras. His theorem was simple, yet beautiful : a² + b² = c²

It has to, because we cannot replace n with 2+1, for example, without ( ) It would look like 6 ÷ 22+1 which is not allowed.

Now you have the likes of this guy, who ONLY teaches "left-right", and changes ALL variables like this:
6x²y²z² ÷ 3xyz to 6*x²*y²*z²÷3*x*y*z equals 2x³y³z³ Really??

6x²y²z² ÷ 3xyz = 2xyz and not 2x³y³z³
because:
6x²y²z² ÷ 3xyz means (6x²y²z²) ÷ (3xyz)
for 2 reasons:
1 - a coefficient is part of the term's value, proven below, and as well with the Identity Law.
2 - The obelus is a grouping symbol. (dividend ÷ divisor)

Both 1 & 2 agree with each other. Why? Because true math always does, and never conflicts. If it does, then something is wrong.

this guy's entire premise is this "2n = 2 * n"
But that is not entirely true. You can evaluate 2n by multiplying, but the VALUE 2n must remain the same. You cannot take 6 the expression 6 ÷ 6 and say it is the same as 6 ÷ 2 * 3. It is so absurd it is deafening.
This proves that 2n = (2 * n) and you cannot split any value by inserting a times. We need more people to comment on this video, so that his students don't end up retarded...

It is such a conspiracy in the world that not a SINGLE math site will give you the answer 1.


You cant find a single one. They all must be wrong and the few people here that say 1 must be right?

EVERY MATH SITE IS WRONG? Is that really what Casper, DUCM, etc are saying? Every single site?

If someone can show me 1 math website that comes up with 1 I will agree. Even though I can show 10+ websites with 9.

I just need 1. One website.


Look here. Look how many UP arrows people get for 1. Look how many UP arrows people get for 9.

Not that is proof, but lines up with this thread. For every 10 people 3 will say 1, 7 will say 9.

ALONG WITH EVERY FRIGGIN WEBSITE ABOUT MATH!!!

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

But I am sure it is all a conspiracy.


5-4+1= 2

Not
5-4+1=0

6÷2*3=9

Not

6÷2*3=1

(We all agree we do parenthesis first... that much I am sure of)

Work from left to right when things are equal.

Just get a scientific calculator, do that equation and you'll see that and what all your **** sites are.

Still cant find one huh. I am sure they are all conspiring to give the wrong answer.

I already answered this a while ago but here goes.

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

9

I have done it. It gives 9. If I just use the calculator without changing the equation or settings it gives 9.

Dear Forgotten,

Please stop posting the exact same reply over and over and over.

We get it, you believe everything you find on the internet.


Thank you

LOL, can you tell everyone else to stop posting the same thing too?


Surely the OP doesnt believe the answer is 9. What say you OP?>

9 or 1?

Excellent rebuttal. Have clearly proven me wrong.

My calculator actually gives me a 1. Still, the only thing it means is, my calculator is wrong.

Or more like middle/high school, I was doing 3x3 and 2x2 in 3rd grade. But yeah, funny how glp can work.

132 pages!

You guys are stoned.....put down the bong!

Maybe there are just different ways to do it and 9 and 1 can both be right. But going by pemdas, I got 9.

(1+2) 3

6/2 3


3 • 3 = 9


What's the deal?

That because math has a certain set of rules that must be followed. All the sites are following the rules, and therefore give 9. If you change the rules you will get 1, or 6, or 0. Or some other incorrect answer.


But, lets face it. Every website is conspiring to give the wrong answer and DUCM, Casper are correct.

But multiplication and division are on the same level, even the m comes before the d in pemdas. So, from what I know, you would just go from left to right when dealing with mult. And div., leaving you with 9 for the problem.

No

Math is pure

9 is the only answer
