Our first grade teachers are all autistic. They didn't teach us right.
Math teacher here.
PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction
6 / 2(1+2) - Parentheses: Add numbers inside
6 / 2(3) - Multiplication: Multiply 2 and 3
6 / 6 - Divide: Self explanatory dumbass
It's 1 you inbreds.
"The answer is that this is a badly-formed sentence. ... You can make claims about conventions and what is right and wrong, but really the burden is on the author of the sentence to put in some commas and make things clear. ... Math is not marks on a page. The mathematics is in what those marks represent."
OP here. listen, in order to stop all of this PEDMAS bullshit, we have to argue about how PEDMAS works. I was taught PEDMAS, but others was taught
We need valid points, and proof to back them up.
What are you going on about? Multiplication and Division get done at the same time, left to right, addition and subtraction are done at the same time, left to right.
3x3=9 but 3/(1/3)=9 does as well. Just like 1+2=3 and 1-(-2)=3. They get done simultaneously with equal priority because subtraction is synonymous with adding negatives.
You guys are literally bottom feeders its 1 as in this example straight from a math site.
old fags will say 9.
new fags will say 1.
Formating is unclear. Math as a language,is only sensible if its syntax is concise.
It's only 9 if you read like a retard. In order for the answer to be 9 the problem would have to be as follows
But it isn't is it. The 2 after the division belongs in the denominator of the fraction, not the numerator, so
6/(2[1+2]) is the correct way to read the problem
i read as a :
6 / 2 * ( 1 + 2 )
and result i got is 9
i am a newfag here in the whole 4chan. srsly the hell is wrong with you guys? desinformation is this seriously ? fuck the future is going to be a piece of shiet
No, it's really not. Type it into a computer program the way it is written in the OP, and it will evaluate it as 9.
Multiplication and division have the same precedence level and are evaluated from left to right.
If the writer of it intended you to read it with parentheses like you added, they would have written it with them. The answer to this problem is objectively 9.
6 divided by 2 multiplied by 3. You then complete them from left to right and get 9.
Nope. Multiplication and division have the same priority in order of operations, so they are done left to right. Addition and subtraction have the same order of priority, so they too are prioritized left to right. Pretty basic stuff, really. Just Google it.
