6�2(2+1)=

**chickenallday** · 03-05-2015, 07:45 PM

the level of retard in this thread is amazing

answer is 9. multiply from left to right

threads like these separate normal people from bull blown idiots

**Kestrels** · 03-05-2015, 07:46 PM

What does the question look like, OP?

If it's 6/2(2+1) with the 2(2+1) all in the denominator, it's 1.
If it's 6/2(2+1) with the (2+1) to the side of the fraction, it's 9.

We all gonna make it~

As I understand it, � represents everything to the left of it being divided by everything to the right, while / represents what is immediately to the left divided by what's immediately to the right.

Haven't been on a TI in a while, but are there both � and /? Or just one of them?

1 = 9

**FeedofGains** · 03-05-2015, 07:49 PM

The problem as it is written is 6�2(1+2) , the � cannot be substituted with a fraction bar because they have different ranks on the order of operations. It is an illegal math move to do this. The bar ranks with parentheses, � is interchangeable with *. therefore the problem must be solved as 6�2(1+2) NOT 6 (over) 2(1+2) we do the parentheses first, so 6�2(3), the parentheses are now no longer relevant, because the number inside is in it's simplest form. Every single number has implied parentheses around it.
6�2(3)
(6) �(2)(3)
6�2*3,
or even converting the division to multiplication by a reciprocal (a legal math move)
(6)(1 (over) 2)(3)
are all correct ways to write this problem and mean exactly the same thing. Using pemdas, where md and as are interchangeable, we work from left to right, so (3)(3) or
3*3= 9

It can be interpreted in 2 different ways. Yes you can go left to right and get 9.

But if you finished anything past basic elementary math, you will get 1. You will see it as a fraction:

6
______ = 1
2(2+1)

Apparently I'm dumb, neg me if you wish. Math Harry above me ^

While I still stand by my original assertion the way the problem is written/presented is ambiguous for modern math, I found this an interesting read for you math nerds.

http://www.matthewcompher.com/posts/...symbol-%C3%B7/

"At any rate, the obelus is introduced to represent division on page 8. Previously, the obelus had been used to mark ancient manuscripts that were believed to be corrupt. As it is used in Teutsche Algebra, however, was the first time it is used in a more modern sense. There are pages of sample uses for division and all of them are analogous to how it used today. This is the first known use of the obelus to represent division.
Things get interesting on page 76, however, when the following assertion is made:"

$T\div GG+1 = \frac{T}{GG+1}$

So in that case the answer would be 1.

**mrmk5110** · 03-05-2015, 07:51 PM

strong retards ITT

If OP wanted the answer to be 1, it would look something like this:

6/(2(2+1))

But it doesn't, so the answer is 9.

just one. You are right though that's what � was originally intended for back in the 1800's but it's devolved into "/" now a days. Things change over time. Like i said it's all semantics. Some people interpret the obelus as you stated while others interpret it as"/". I prefer to leave the ambiguity out of it and just use parentheses to clearly state how the problem should be solved. I've never used the obelus in engineering.

I read that article as well. but the obelus is largely not used in that way anymore therefore making the answer 9. Agreed though, the confusion comes from different interpretations of the obelus

9=1

1=9

Dont matter how you write it bro.

The answer is still 1

Being a fraction has nothing to do with the order. Your definition of a fraction is wrong also. A fraction is a number that is less than 1...

6�2 is not a fraction
6/2 is not a fraction

The better saying is "does 6� 2 PRODUCE a fraction." An that answer is no it does not. 6/2 = 3 which is not less than 1 therefore it is not a fraction.

ignore this red.

**Seatard** · 03-05-2015, 08:03 PM

Egotistical miscers always assume the question is written in American numbers.

The internet is worldwide these days. Maybe the question is in metric and the answer is indeed 1. Maybe it's using the Kansas system and the answer is Jesus or the answer is taco because it's a Mexican equation. Fuk, wake up! It's not all about you.

**OhioBoy21** · 03-05-2015, 08:06 PM

I took math last year and it can equal 1 or 9 depending on what order you solve it

**AlleyBoy** · 03-05-2015, 08:06 PM

Then why the **** was I taught PEMDAS.

**thercias** · 03-05-2015, 08:06 PM

- subhuman iq miscers think the answer is 1

lol u wot m8? fractions can be greater than 1

Your right...Good check

Fractions are numbers that are not whole.

but still 6/2 is not a fraction. for it gives you a whole number.
