Multiplication first -> 3 x 6 = 18
Addition -> 18 + 2 = 20
Subtraction -> 3 - 20 = -17
Answer is -17
All you worthless NEETs brag about bettering yourselves, and you can't even Order of Operations?
I know this is bait but fuck you anyway
Maybe I'm getting too old for the Internet. Is this supposed to be difficult? Please excuse my dear aunt Sal. Multiplication and division are the same operation, so are addition and subtraction.
I sweat, you millennials have been really handicapped by your new ways of doing math. The fact that this is something difficult for you makes me question what I was taught.
Going in the order of PEMDAS, following it left to right would equal
3*6 = 18
18 + 2 = 20
3 - 20 = -17
Going with PEMDAS but defaulting to left to right with both addition and subtraction on the table would equal
3*6 = 18
3 - 18 = -15
-15 + 2 = -13
All in all a stupid trick question that depends on how you were taught to use PEMDAS.
There is only one way to use PEMDAS. Mathematics is an objective science. An equation with only one unknown element can't have more than one solution.
Also in the first part you forgot that the 18 is negative, so you get -16, not 20
>Mathematics is an objective science
Oh boy. Another ignorant fuck trying to look clever.
I know some people were taught to follow PEMDAS to the letter, as in going P->E->M->D->A->S which is why I formatted it like that. Addition comes first in PEMDAS so that's why it was positive 18.
The other way that I've seen and heard it taught is P->E->MD->AS where you follow the default left to right of the equation, depending on the problem itself and not the order of operations.
Also your statement is incorrect anyway as it would make no sense for the 18 to be negative, it hasn't been modified besides being a factor of 3*6.
If we write the equation in the OP as 3-3*6+2 = x, only has one value that satisfies the equation correctly. Of course if we were to enter with 2 or 3 variables we could have infinite results, (and two results would be possible if x was square rooted), but this level of maths is as objective as it gets. -13 is the only answer.
Yes it does make sense for 18 to be negative you imbecile, if you remove the first 3 and the 2 you get (-3*6), the signal doesn't disappear on thin air. It's still there to be considered and it changes the result to -18
Mathematics is objective, yeah, but it's not a science.
But, first, why would you randomly remove the 3 and 2? Following PEMDAS you would just get 3*-18+2 with your logic.
I wasn't taught the poem, just the order of operations.
Because since first you need to sulve the multiplication. The elements of the multiplication are -3 and 6. They are -18
Adding and subtrating only comes later and you have two elements adding, a 3 and a 2.
So You could rewrite the equation like
-18 + 5
5 - 18
2 - 18 + 3
3 - 18 +2
All these are equal to -13, which is the only possible result, since this equation only admits ONE solution
I see what you mean now. But that's still not following PEMDAS, that's just being anal about how the problem is sorted. Also, where did the 5 come from? 3 and 2 never got added together. I do agree that -13 is the only solution but your ignoring parts of it only make sense because you want them to.
5 is 3+2. Since you already solved the only multiplication, you could write -18 + 3 + 2, or simply just directly write -18 + 5. You should follow PEMDAS, however from the moment all multiplications and divisions are out of the way, adding or subtrating in any order ends up giving the same result, altough we usually do them in order left from right for the sake of simplicity
The point I was making is that -13 is the only answer
/b/ pls fuck off with your threads. you arent welcome here you newfag.
I know this is bait but you got me good.
No one can be this retarded
because if you add the brackets on -3*6, the - decomposes into +-, not *- you imbecile
nigga, the expression is invalid,
What is appliable to a simple addiction also applies to multiplications and divisions. Mathematics is an unversal languages, not like spoken languages that change with world zones
You were either taught wrong, or didn't pay attention and solved it wrong. Either way if you went though the effort of contacting a mathematician from America, Australia, Germany, CHina etc, they would all give you the same answer -13
I doubt I'm wrong. In high school I was almost top of my mathematics class and there was over a 100 people in that class.
I was one of the first to enroll at my country's first engineering college.

>get put in charge of pretty important calculations
>turns out maths are done differentely in America lel
>nothing adds up with the rest of the work of other engineers
>six dead during test
If an idiot like you that can't even manage to solve correctly a basic equation was at the top of maths class I weep for your country
Holy shit are you dumb. I saw what you were trying to do >>26433571 here. If you're going to use parenthesis, it should go like this:
3 - 3 X 6 + 2
= 3 - ( 3 X 6 ) + 2
=3 - (18) + 2
= -15 + 2
My country will probably be ahead of yours in the future.
English is one of two languages I speak. Can you say the same?
Coming from modest beginnings doesn't make me wrong and you right.
Actually yes it does, because the only true solution to this equation is -13 and since you got it wrong you're wrong
I also have a huge suspicion that you're Indian, so poo in loo, designated shitting streets etc
For reference I'm billingual and I'm currently learning a third
I'm tired of this. We'll have to agree to disagree.
Neither of us can be proved right on the internet.
But I'll be taking this maths problem to my lecturer to see what he has to say.
