Saw this on another post...
[quote]6 / 2 (1+2) = ?[/quote]
The answer is 9.
Because if the order of operations...
6/2(1+2)
Start with parentheses so it would next be
6/2(3)
Order of operations states to do division and multiplication in what ever order they are in from left to right.
3(3)
3⋅3=9 so the answer is
[spoiler][b][i][u]9[/u][/i][/b][/spoiler]

16 通の返信[quote]6 / 2 (1+2) = ?[/quote] The [b]/[/b] implies that 2(1+2) is all under 6. A fraction. Making it in reality 6/[2(1+2)] it is all seen as under 6 so we drop the second pair of brackets. Op has it written as above and is answered below. 6/2(1+2) 6/2(3) 6/6= 1 However if you were to write it like this 6÷2(1+2) Then the way Op answered it would be correct. As it is not seen as a fraction, it will be read as this: 6÷2(1+2) without the invincible second pair of brackets.solved as follows 6÷2(1+2) 6÷2(3) 3(3)=9 TL;DR: Its all in how the equation is written

4 通の返信Ahhh you slick bastard!!!! It is 9. Hey guys so the problem is that we're treating the whole thing as a single function. Thus implementing the distributive property so 6/ 2(2+1) = 6/ (4+2) = 6/6 = 1 But apparently the problem is two separate functions. 6÷2 [b][i]times[/i][/b] (2+1) Its because of how it's written that there's any discrepancy

4 通の返信Explained that it truly is 1. Google is wrong. The 3 stays in the parentheses until finished being dealt with. It's not a question of what comes first multiplication or division but rather the fact ppl dont remember parentheses come before all.

51 通の返信yamにより編集済み: 12/6/2015 5:04:30 PMactually, it could be both, depending on how you look at the problem. if you see the problem as being two separate things, then it is 9, but if you see it as one thing, then it will be 1. 2things 6/2 separate from (1+2) 6/2 is 3 then 3(1+2) is 9 [i][u]but[/u][/i] if you see the (1+2) as being in the denominator then 6/(2(1+2)) 2*(1+2) is 6 6/6 is 1 tldr: both are right

28 通の返信Sainyuleにより編集済み: 12/6/2015 9:02:46 PMEveryone seems to think that you have to multiply that 2 first. That is not the case, it would be the case if the problem was 6/(2(1+2) this would indicate that 2(1+2) is all involved in the division of 6. But since the parenthesis don't exist you can simply divide. You now have 3(1+2). Multiply that 3 over to get 3+6 which equals 9. You don't need PEMDAS at all. Just people who didn't pay attention in math use it because they don't quite understand how things work when parenthesis aren't there to point it out for them. PEMDAS just -blam!-s everything up tbh.
