6÷2(1+2) = ???

[Kabasares]

So the other day, my friend brought this problem up in my AP Chemistry class that soon spread into a huge debate among students and teachers at my school. What do you think it is?

[Elf]

1

[Logsdon]

It's obviously 1

[Goodwin 1st MRB]

1, no question.

[Peaker]

9.

Operation priority goes thus:

1. () and exponential

2. Divisions and multiplications

3. Additions and substractions

Furthermore, when there's no symbol, it's automatically assumed to be a multiplication. We also read left to right.

So:

6 divided by 2 (1+2)

6 divided by 2 x (3)

3(3)

9

[Brown]

pretty sure it's 1, because don't you 6/2(1+2) = 6/2(3) = 6/2x3 = 6/6 = 1

??

Taken from there: "If an expression involves two or more operations at the same level of priority, those operations are done from left to right."

[Brown]

Always thought multiplying was higher priority

[Magic 1st MRB]

9.

1. () and exponential

2. Divisions and multiplications

Furthermore, when there's no symbol, it's automatically assumed to be a multiplication. We also read left to right.

So:

6 divided by 2 (1+2)

6 divided by 2 x (3)

3(3)

9

ITS 9.

Work left to right if it is in the same tier.

() has priority - so (1+2) first... since that is 3, it's multiplied by 2.

Then the division is applied.

[Goodwin 1st MRB]

We clearly need Dobbles to weigh in on this.

He has a degree in mathematics.

[Kabasares]

I initially thought it was 1 and then 9, but I think its 1 again.

[Peaker]

I used the parenthesis for clarity, but actually what happens is:

6/2(2+1)

Then

6/2x3

Since the priority is the same for x and /, we read left to right

6/2=3

3x3=9

[Yamagata 1st MRB]

In programming, () takes precedence. So that's how I do my math.

[Kabasares]

What does this simplify to?

6/x(1+x)

6/(x + x^2)?

Or (6/x)(1 + x)?

[Peaker]

So you got a parenthesis, let's do it first

6/X x X+1

Left to right:

6/X is nullified if you multiply it my the same denominator (ie: 1/2 x 2 = 1) so 6/X x X=6

So we're left with 6+1=7

It's normal proceedure to always put the letter first, but if you keep the 1 first:

6/X x 1+X

So we'd end up with (6/X)+X

What's this? My penis divided upon a couple of females multiplied by the number of possible cumshots/children?

The answer is null/none of the above, because my penis is a solid inch bigger. Case settled.

Unbelievable.

[Dawson 1st MRB]

Lets state the equasion differently.

6 / 2 * (1+2).

so it's really a question of if divide or multiply has higher priority

[S. Richards]

Unbelievable.

Got my degree in Golds Gym. School loan was only $19.99 a month for 2 years, pretty good deal.

[Logsdon]

6÷2(1+2)

6/2+4

3+4

7

[Griswold]

6÷2(1+2)

6/2+4

3+4

7

^ what are doing ?

fyi I input this in Wolfram Alpha i got 9. Check your self here

[ClickClickahShit]

FUCK I thought I was actually smart... I clicked 1.

Conclusion: I'm going to pull a Billy Madison and go back to grade school... See you in a year!

P.S. Fuck you for ruining my day with this mathematical tomfoolery

[Parker 1st MRB]

IT depends how you write it:

The way Kaba wrote the question, the answer would be 1.

hes right, u need to consider everything around de ( ) first.
