Parenthesis: (1+2) = 3

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

Multiply/Divide from left to right: 6/2 = 3

6/2(3) = 3(3)

Multiply/Divide from left to right: 3(3) = 9
---

9 I think (if I am remembering order of operations correctly.)
---

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

6/2=3

1+2=3

(3)*(3)=9

9 is the correct answer

You don't multiply 2 and 3, you divide 6 by 2 first.

This. Its six divided by (2x3), not 6/2 x 3.

it's pretty important to have a standard way to write equations. just saiyan

These are devious because some people see the slash as a division marker in a single-line equation, while others see it as representing a fraction with 6 on top and both the factors 2 and (1+2) on the bottom. Different calculators may also determine the input differently based on default or custom settings.

No, it's not. If it was, it would be written as 6/(2(1+2))

I got 9

I also put this shit on wolframalpha, wolframalpha also got 9

and I trust the wolf over all of you when it comes down to match tbh

problems like this are why I abuse parentheses when typing into calculators or when programming

See I did it like that too. But googling it, apparently this is wrong.

What do you know.

Yeah.

If the problem was written like this;

6
--------
2(1+2)

It would be 1.
But it ain't.

The 2 is a coefficient of (1+2). That takes precedent over being divided into 6. People who think the answer's 9 probably also think haikus require a specific number of syllables, and different parts of the tongue are designated to taste sweet, sour, bitter, and salty.

You do what is inside the parentheses first, before you multiply 2 to all the numbers in the parentheses. There is no coefficient because there is no variable.

Look even though multiplication comes before division in PEMDAS, they are interchangeable, same with addition and subtraction. The rule is whichever comes first left to right. And some people think that because a number is next to a parenthesis, it takes precedence, but it doesn't. Once you solve for inside the parenthesis, treat it just like it were to have an x there.

nah. if you're to declare that 2(1+2) needs to be solved as a subset of the equation before dividing it into 6, it would need to be wrapped in an additional set of parentheses

it's really the only way to express equations in text without using Latex or some other graphical notation

BEDMAS says it's 9.

Sorry I forgot the second half of my post. You do what is in the parentheses. Then you divide 6 by 2. You don't distribute 2 to the parentheses because there is no variable in them.

Is it 6 divided by 2, multiplied by (1+2)?
Cause if so, the answer is 9.

or is it 6 divided by 2 multiplied by (1+2)?
Cause if so, the answer is 1.

That is one reason some of these types of topics are stupid, because not all math problems are written in one line.

The true answer is meme

It's 9 or depending how you interpret the division sign.
---

0.999... can't equal 1 because what about 0.999...9
---

If the slash is mean to represent a fraction rather than a division symbol than it should be written "6/(2(1+2))" and the answer would be 1. However since it isn't the assumption should be that the slash does represent a division symbol in which case the answer is 9. That said, any proper mathematician would write this equation "(6/2)(1+2)" to avoid any possible confusion. The way it's written in the topic title is done on purpose to be misleading.

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

Divide 6 by 2

3(1+2)=???

Distribute

3+6=???

Answer is clearly 1 you math failures

PEMDAS is just some over simplified garbage little kids are taught in school, no different than the haiku example I brought up, or when bad English teachers tell their students not to start sentences with conjunctions. 6/2(3) is not the same as 6/2*3. Some spacing might help. 6 / 2(3). Is not the same as 6 / 2 * 3.

No because that expression (not equation btw) is simplified to 18, not 9.

Yeah I typoed that and added an extra 2.

I never heard of PEMDAS until years after I graduated on this very web site. Sounds like a very poor teaching tool that taught students that multiplication/division and addition/subtraction are not equal operations when they are.

As a math teacher who uses PEMDAS as a reference I also teach that MD and AS are equal and you carry them out going from left to right instead of M before D or A before S.
