Statto Posted April 29, 2011 Share Posted April 29, 2011 If it was written 6?2x(1+2)= 9 but it's written 6?2(1+2)= 1. Correct? Link to comment Share on other sites More sharing options...
craigie jambo Posted April 29, 2011 Share Posted April 29, 2011 What's IN the brackets must be resolved first. To be fair it is an ambiguous expression mixing two different notation styles intentionally. What's after '?' goes to denominator underneath; zero ambiguity Link to comment Share on other sites More sharing options...

davemclaren Posted April 29, 2011 Share Posted April 29, 2011 The problem to solve is: 6/2*(1+2) 6/2 evaluates to 3 1+2 evaluates to 3 Multiply 3 and 3 6/2*(1+2) evaluates to 9 The final answer is 9 Link to comment Share on other sites More sharing options...

P-Dizzle Posted April 29, 2011 Share Posted April 29, 2011 Mathway.com says 9. That's because it is not the same. They are taking the 6/2 and then multiplying it by 3. That is not what you are to do here. 6 is on the top, on the bottom is 2(1+2). The (1+2) is not isolated from the 2 so you cannot leave it out and divide 6/2 then times by 3. There is no contention here, just people's inability to take 2(1+2) as one entity and solve it. Link to comment Share on other sites More sharing options...

Mid Calder Jambo Posted April 29, 2011 Share Posted April 29, 2011 Can the 1 sayers come up with any actual evidence rather than just opinion? Well, for those in the Republican camp, the evidence is quite simple. Anything to the right hand side of the division sign goes underneath the line so the number 6 is divided by the result of adding the multiples of 2 times 1 and 2 times 2. 2 times 1 is 2. 2 times 2 is 4. 2 plus 4 is 6. 6 divided by 6 is 1.

Statto Posted April 29, 2011 Share Posted April 29, 2011 The real question goes deeper than is the answer 9 or 1. It seems to be is the "2" attached to the bracket or is the "x" implied between the "2" and the "(1+2)" separating them? I guess it's down to interpretation of the sum.

I already agreed earlier that if you re-express it as a fraction you get 1. If you leave it as is you get 9.

What you're taking about is (6/2)*(1+2), so equally I can say that you are not using the same expression. Link to comment Share on other sites More sharing options...

Mid Calder Jambo Posted April 29, 2011 Share Posted April 29, 2011 But multiplication and division rank equally so you do it left to right. 6 divided by 2 is 3, times 3 is 9. I think you are at the pulling of the plonker here, Dave, for the sake of comedic effect As I stated in an earlier post anything to the right hand side of the division sign goes underneath the line. Yes you are right. 6 is divided by 2. But it is divided by 2 which has been multiplied by three first, thereby making the divisor 6 and the final answer 1.

Do you just teach everything from a textbook and calculator without understanding the maths behind it? Can anyone in the "1" camp actually provide any evidence at all that 6/2(1+2) = 1 apart from their own opinion? I love how calculators, spreadsheet programs and maths websites are all apparently 'wrong!' :) :) Link to comment Share on other sites More sharing options...
