phantomlady1101 59 Report post Posted May 1, 2011 Lol, It's easy or not!!! I believe it is 1, in Casio 500 MS (calculator) tells is 1 but my teacher said is 9!!! Quote Share this post Link to post Share on other sites
IdentityUnknown 216 Report post Posted May 1, 2011 Assuming you don't want us to go wacko off into Math (aka. mess it all up), I'll go with my answer. It's easy to be fooled. Order of Operations. PEMDAS Quote Share this post Link to post Share on other sites
Anti-APTX4869 181 Report post Posted May 1, 2011 yea it is 9 and oops i clicked wrong one you want to know why it is 9? Well, actually, it is also 1 too. Heres the answer to this trick: Reveal hidden contents 6÷ 2(1+2) well, here is the trick. if you write it like that, there's 2 ways to solve them. 6÷(2(1+2)) = 6÷(2(3)) = 6÷6 = 1 or (6÷2)(1+2) = 3(3) = 9 This actually depends on how you look at the problem.

phantomlady1101 59 Report post Posted May 1, 2011 My teacher said: 6÷2(1+2)= 6÷2x3= 3x3 = 9 But my friends and me: 6÷2(1+2)= 6÷(2*3)= 1 Quote Share this post Link to post Share on other sites

IdentityUnknown 216 Report post Posted May 1, 2011 On 5/1/2011 at 6:29 AM, phantomlady1101 said: What??? My opinion is 1!!!! The thing is, the number 2 was never in the brackets. There was never an obligation to multiply it first. So the equation would be: Reveal hidden contents 6÷2(1+2) <-Beginning Equation 6÷2(3) <-This is where you started going off track 6÷2x3 <-Since there is no obligation to put 3 in brackets anymore, we can take them out so it makes more sense 3x3 9 <-Final Answer I hope that makes more sense.

You can ask Google!!! It's tells 9 but when it follows gcalctool 5.32.0 it will be 1!!!

phantomlady1101 59 Report post Posted May 1, 2011 My dad just got home, I ask him, he said: 6 ___________ 2(1+2) Quote Share this post Link to post Share on other sites
Anti-APTX4869 181 Report post Posted May 1, 2011 Like I said, both ways are correct. It's just that there's 2 ways to look at it. ...6 ----- 2(1+2) or 6 --(1+2) 2 Quote Share this post Link to post Share on other sites

Misaki-chan 164 Report post Posted May 1, 2011 Why exactly is there mixed answers? I think the answer's nine. Quote Share this post Link to post Share on other sites
ikg 2 Report post Posted May 1, 2011 6/2(1+2) = ? I think 6/2 = 3 and 1+2 = 3 so, 3*3 = 9 But my friend said 2(1+2)= 6 and 6/6 = 1 This question has two solutions ? However, I think the best answer is 1. Quote Share this post Link to post Share on other sites
dreznovk 5 Report post Posted May 1, 2011 Always perform what in '()' first --> 1+2=3 We have : 6 / 2 * 3 If we have both division and multiplication, we do it from left to right: 6 / 2 = 3 Then 3 * 3 = 9 The answer is 9, is it right ? Quote Share this post Link to post Share on other sites
