Multiplication first -> 3 x 6 = 18

It's -16 dipshit. Adding and subtracting works in reverse order with negative numbers
>>
>>26432617
-17 is the answer.
>>
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.
>>
>>26433101
Amending the second statement, going from left to right in the *equation*, not going left to right following PEMDAS.
>>
>>26433101
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.
>>
>>26433151
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.
>>
>>26433171
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.

>>26433209
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.
>>
>>26433235
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.

its right though. 0x8 hex coverts to 8 dec.

>>
>>26433339
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

>>
>>26433472
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.

3 - 3 x 6 + 2
3 x (-3 x 6) + 2

Answer: -52

You guys are fucking idiots.

>>26432617
Notice that the variable ?? is in the sentence. It reads "only 4??". Unless you are a retard than ?? = -13, so the answer is -52.

>>26433101
There's only one way to correctly order your operations.
>>
>>26433610
Of course there is, the second way is objectively correct. I'm just attempting to explain the difference in people's answers.
>>
>>26433549
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
>>
>>26433637
OK. I completely agree with you, -13 is the only answer here. I just tend to keep it simple. Thanks for the insight though!
>>
>>26433586
It's -52.

The 'minus' symbol belongs to the '3' in (-3 x 6).

That leaves you with: 3 (-18)

In these instances you must multiply.
>>

If you're going to think like that, you get 3 + (-3*6) you dumbshit, That 3 has a + on the left and a - on the right, how the fuck would it suddenly multiply outta nowhere?

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
