Rick Grimes Posted April 28, 2011 Share Posted April 28, 2011 So it is 1? I'd say so http://en.wikipedia.org/wiki/Order_of_operations#The_standard_order_of_operations 1 + 2 is definitely done first according to the above. I guess you could debate over whether the 2 * 3 or 6 / 2 is done first but as the multiplication is being done on the product of the sum in the brackets I'd resolve that first.

Isn't multiplication and division treated equally therefore you go for the one leftmost in this case division and therefore end up with 9...

I P Knightley Posted April 28, 2011 Share Posted April 28, 2011 Brackets Exponentials (powers) Division Multiplication Addition Subtraction The answer's 1. Bracket first and all that goes with it (3 x 2); then divide. No fee. My pleasure. Link to comment Share on other sites More sharing options...
Rick Grimes Posted April 28, 2011 Share Posted April 28, 2011 Isn't multiplication and division treated equally therefore you go for the one leftmost in this case division and therefore end up with 9... that's where you can argue it either way. as the multiplication is being done directly on the brackets I'm counting that as part of that operation. if it was 6/2*(1+2) then you'd definitely be right, as is I'm not sure.

shaun.lawson Posted April 28, 2011 Share Posted April 28, 2011 I don't understand how people get 9 I get 1 Nine's the answer most people arrive at - because not realising the difference it makes, they do the 1+2 first. That's 3 - then they go on to multiply the sum of 6/2 (in other words, 3) by the 3 they already have, which makes nine. As others have said though, the answer's 1.

Shaun's explanation is better as it stresses that the sum inside the brackets is only part of the overall operation that's being done at that stage & hence before the division in the overall problem. Talk me through your working out of it because from the way I see it using BODMAS we check if theres brackets first and do 6/2(1+2) = 6/2(3) we then go back to the start and left to right and using bodmas again we use division on 6/2(3) to get 3 seeing as the brackets have already been dealt with we're then left with 3(3) which is equivalent to 3*(3) and get 9. My understanding of the brackets part was you dealt with the operation inside the bracket, the just because there was a value outside it you don't go from 6/2(3) (There is no operation inside the bracket here, just a value) to 6/6 Link to comment Share on other sites More sharing options...

It's all there in the equation. You just have to see it. I know what 2(3) is. But you have 6/2(3). There is no operation inside the brackets therefore the first part of BODMAS at this point is DM and going left to right the first occurence is 6/2.

I'm taking the operation of multiplying on the brackets as more important than the division as the bracket still exists - until you fully resolve the brackets, inside & out, then they are paramount.

There is no operation inside the brackets therefore the first part of BODMAS at this point is DM and going left to right the first occurence is 6/2. The actual correct theory is BOMDAS. Some folk use BODMAS but the actual proper way is BOMDAS. This means you get (Multiply first) so the problem becomes 6 divided by 2x3 which is 6 divided by 6 which is 1 Link to comment Share on other sites More sharing options...
