Gaz6002 Posted November 10, 2011 Share Posted November 10, 2011 Variations of this have been all over FB for the past few days. ...how come you didn't put the right answer in the poll? Link to comment Share on other sites More sharing options...

caseys Posted November 10, 2011 Author Share Posted November 10, 2011 This all stems from an argument about it with a bunch of programmers. There are several ways to read this and also execute it! Link to comment Share on other sites More sharing options...

stevie_b Posted November 10, 2011 Share Posted November 10, 2011 This all stems from an argument about it with a bunch of programmers. There are several ways to read this and also execute it! Doesn't the generally-accepted operator precedence define a single correct way though? I suppose then it's an issue of whether one follows the generally-accepted way.

sdistc Posted November 10, 2011 Share Posted November 10, 2011 I was always taught to apply multiplication and division first, unless there is a closed bracket to imply an operation to be performed first. Link to comment Share on other sites More sharing options...

Gabriella Posted November 10, 2011 Share Posted November 10, 2011 5+5+5-5+5+5-5+(5 x 0)= 15 Link to comment Share on other sites More sharing options...
Westy Posted November 10, 2011 Share Posted November 10, 2011 But there are no brackets in the sum above!? Otherwise correct. Link to comment Share on other sites More sharing options...
Gabriella Posted November 10, 2011 Share Posted November 10, 2011 Brackets show how was it done ..so now without 5+5+5-5+5+5-5+5 x 0= 15 Link to comment Share on other sites More sharing options...
TTRickeh Posted November 10, 2011 Share Posted November 10, 2011 Hmmm I voted 0 but now I think it's 15. The way it's written with a space at the end for the zero kind of implies that the whole thing is multiplied by 0 at the end (like (5+5+5-5+5+5-5)0 ) but if you write it all with the same spaces it's 5+5+5-5+5+5-5+5x0 which is the same as karolina's post (although there are added brackets they don't make a difference to the outcome here) given that you have to do multiplication before addition and subtraction (bodmas). Those are my thoughts Link to comment Share on other sites More sharing options...
Pixelfill Posted November 10, 2011 Share Posted November 10, 2011 I voted 15, but I was probably wrong! I don't know what the answer actually is, because it would depend on the order you carry out the subtractions. 5+5+5-5+5+5-5+5x0 BODMAS says you should do the multiplication first 5+5+5-5+5+5-5+0 Then you should do the addition 15-15-5 but there is no convention to the order of subtractions. so the answer could be either 0-5 = -5 or 15-10 = 5 Interesting - and I hate you for proving my inadequacies.

edinlexusV8 Posted November 10, 2011 Share Posted November 10, 2011 15 obviously!! Link to comment Share on other sites More sharing options...
Scott Posted November 10, 2011 Share Posted November 10, 2011 Zero is the correct answer. Those who say 15 spend too much time with their calculators and not enough time using their brain. Calculators auto bracket for multiplications and divisions so they will always give the wrong answer. Link to comment Share on other sites More sharing options...
edinlexusV8 Posted November 10, 2011 Share Posted November 10, 2011 Dont think we need calculators for this. 15 is the correct answer .. Link to comment Share on other sites More sharing options...
Scott Posted November 10, 2011 Share Posted November 10, 2011 Dont think we need calculators for this. 15 is the correct answer .. Are you kidding? You think 20 x 0 is 15? Link to comment Share on other sites More sharing options...

Scott Posted November 10, 2011 Share Posted November 10, 2011 Bodmas??? That's the same as auto bracketing though. Link to comment Share on other sites More sharing options...
Ross C Posted November 10, 2011 Share Posted November 10, 2011 Bodmas doesnt apply because of the spaces between the last 5 and x 0. It makes 20 x 0 therefore 0 as Scott says Link to comment Share on other sites More sharing options...
edinlexusV8 Posted November 10, 2011 Share Posted November 10, 2011 Space is not an operator ... Link to comment Share on other sites More sharing options...
