How can be people be so stupid?
6/2(2+1)=? 1 or 9?
obviously 9... 6/2(1+2) => 6*1/2*(1+2) => 6*1/2*(3) => 3*3 = 9
go back to school...
for people that still think its 1, here is a good read
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

I'm assuming that what you're raging about in your comparison is what computer text in math means.
Both, if looked from a logical point of view, can be correct. Technically though, / stands for ÷ and thus simple BEDMAS rules apply.
Shouldn't call people stupid for perception issues though, that's kinda naive. -

i called them stupid because they said that the multiplication has priority over the division, and also even after my explanation they still though i was wrong and called ME stupid... -
How so? It's all in perception. Even though we know that / represents division, it's not a far stretch to perceive it as being "over" as Emotion states. While that is wrong in general, who's to say that's not what the original "creator" had intended?GringoLixo wrote: »Lol.
If someone thinks it's 1, then there's no further argument required.. they already showed how dumb they are

it's 9, some people use calculator that arn't graphic one. Basic calculator doesn't do the priority of the operation. So that gives 1.
() , then the ^ (and square root), then the /,* then the +,- all this from left ===>>> right.
Human invented school to make people use their head but some still rely too much on the machine.
(same goes for the people that signed a petition agains't the h2o (water)) they don't think they just do. -

For someone to think it was 1, it would have to be .. honestly, I don't even see how someone can think it was 1. -
Actually he's right. In simple functions like these it may not make a difference, but in complex algebraic equations following the order of operations makes a large difference.[MOD]Talonblaze wrote: »Depending on what the actual method of calculation is, its correct.

The only logical way it can calculate to one is a simple perceptive mistake. If they mistook the question to be:GringoLixo wrote: »For someone to think it was 1, it would have to be .. honestly, I don't even see how someone can think it was 1.
6
= 1
2 (2+1) -

that would be a perception mistake but the people i asked they said it was 1 because the multiplication has priority over the division which is not true -
Well, an electrician can see people as dumb because they can't change their light switch (I don't know to do that). People can forget things, never had the change to learn those things, and so on.GringoLixo wrote: »Exactly, I don't see how someone can get it wrong. -

I don't even see how unless it was directly before the actual brackets themselves. Since each section has to follow bedmass. Sections being, out of bracket to the brackets themselves. -

Changing a light switch is different from 1+2
But, I understand your point
