discussion ATRL: I have a math emergency: 6÷2(1+2)=?

[Attitude]

PEMDAS is a lie!

[LittleStarmen]

This is badly formated to beging with

 

its actually 

 

6

/

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

 

6/6 = 1

It's both 9 and 1, depending how you view it.

The issue is the formatting of the equation.

 

6÷2(1+2) seems fairly easy. 
 

(1+2)=3, so we get 6÷2(3)

 

According to PEMDAS, the order of operations is Parentheses, Exponent, Multiplication or Division, Addition or Subtraction.
 

PEMDAS operates from left to right, so for some, that would mean dividing 6 by 2 and getting 3 which then multiplies by 3 and gives you 9.

 

For people who resort to multiplying whatever is next to the parentheses as part of the P, the answer then becomes 2 times 3, which gives you 6 and then you can divide by 6 and get 1. 
 

There isn't a correct answer with the horrible formatting of this problem by the way.  
 

After elementary, using this ÷ symbol is a joke, any division should be expressed as a fraction rather than using ÷. 
 

If this were formatted to match actual practical mathematic problems, it would look like this:

 

6

—

2(1+2)

 

in this case, the answer is obviously 1, but when you use this cursed ÷ sh*t, you're losing vital information which leads to these debates.

It's not about multiplication coming before division that people are having a problem with by the way, it's the fact that you still have the parentheses after getting the 3, it's debated whether the numbers outside the parentheses that multiply with what's inside would count for the P or the M since they're linked together, without the x symbol. 

 

Also, even if you didn't give priority to the multiplication, the actual way of viewing this is as a fraction where 

 

6

–

2(1+2) 

 

in this case where we have a correct and concise view of the equation, there's no room for debate and it'll always be 1. 
 

Writing it out like they're giving it to us with the cursed division symbol is the reason why this is even being debated, but it's useless, since no one apart from elementary kids use it.

(1+2) is in the denominator since it's next to the 2 outside of the parentheses, that implied multiplication applies to the 2, not the 6. 
 

Even if let's say the (1+2) was in the numerator, it would be 18/2, not 3/2. 

Oh a check needs to be cut!  @Iceland

I meant the part barring the initial 6*

6*3/2 = 9

I see, but the 3 inside the parentheses is still next to the 2, which calls for a multiplication. 

[cOe]

The way I was taught, the **** outside and inside of the brackets happens simultaneously, but doesn't interact at first. Hence 3*3=9

I was taught that the inside of the brackets needs to be solved first.

Now which math teacher lied to us

Same

 

2(1+2) = 2(3) = so you ger rid of parenthesis first = 6

 

and then you the rest  6/6

[punisher]

6÷2(1+2)

(6÷2)(3)

(3)(3)

9

[BnPac]

1.

I'm not good at algebra. Sorry

I get those who voted 9 or 1. They both have proper explanations.

But why tf 8 losers voted for 6 or 3? 

[Gelato]

143 

[Illuminati]

Neither 9 nor 1 will give us the answer whether math is related to science

 

[Slap]

The only correct answer is it equals LG7's first week sales.

not ppl saying "by what i was taught it's 1" it's math, it's the same everywhere  and it's obviously 9.

It's 1 isn't it?

[CBC]

this type of representation is ambiguous that is why we use fractions. don't yall get tired?

[dumbsparce]

It's 2(1+2) therefore the answer is 9

If it was [2(1+2)] the answer would be 1

 

Spoiler

I think

 

[Apolonio ₃₄]

I got 9 and I'm sticking with that. 
 

[Cruel Summer]

As written, it's valid to interpret as both 1, because some sources suggest the implicit multiplication of 2(1+2) occurs before the division because of its implicit nature, or 9, because other sources suggest otherwise. This is why we don't write actual equations this way and would instead use fraction notation to make it clear whether this is (6/2)•(1+2) or 6/(2•(1+2)).

 

I voted 1 because people pretending implicit multiplication doesn't exist is annoying
