king ubu Posted March 10, 2015 Report Share Posted March 10, 2015 not sure what/who pimdas or pemdas is, but if you just add things chronologically as you read (as jazz musicians do when they improvise a chorus, you might say), it's of course 56 Quote Link to comment Share on other sites More sharing options...

jazztrain Posted March 10, 2015 Report Share Posted March 10, 2015 The answer, as some others have noted, is 50. There are some basic rules of arithmetic, also carried over into programming, whereby multiplication and division operations take place before sums and additions. I'd parse it as follows: 7 + (7/7) + (7 x 7) - 7 = 7 + 1 + 49 - 7 = 50 Quote Link to comment Share on other sites More sharing options...

ejp626 Posted March 10, 2015 Report Share Posted March 10, 2015 Every year it seems that this order of operations stuff crops up. The odd thing is that it turns out at least some software is not programmed with the proper order of operations (or it might lose track after 4 or 5 operations). I find it is an important reminder that you really ought to use brackets to ensure the program is doing what you intend it to do. Quote Link to comment Share on other sites More sharing options...
aparxa Posted March 10, 2015 Report Share Posted March 10, 2015 Naah, no need of brackets, if the math software isn't well programmed enough to compute the most basic operations, use another one. Quote Link to comment Share on other sites More sharing options...
ejp626 Posted March 10, 2015 Report Share Posted March 10, 2015 Not trying to argue that Excel is great math software, but if you poke it (or nearly any other software) there will be something that was programmed differently from the way a math professor would do it. In this case it has to do with exponentiation.I found this an interesting (if long) exchange on the issue: http://mathforum.org/library/drmath/view/69058.htmlBasically, I would still argue that you ought to start throwing brackets around once you get past 3 or 4 terms and operations.

By default, multiplications/divisions are always performed before additions/subtractions. If the intent is otherwise, group it accordingly. Otherwise, yes, 50.

JSngry Posted March 11, 2015 Report Share Posted March 11, 2015 You know, shit like this is open to interpretation, like, you know, WHO SAYS? THEY SAYS! and all that, but that's Art Math, Interpretational Equationality. And that's cool, all kinds of non-traditional equations to get to alternate conclusions, but if you wanna get paid right and/or not fall out of that tree because you choose to interpret gravity before recognizing it, hey, learn how "they" do it. Cover that and THEN interpret. Quote Link to comment Share on other sites More sharing options...
