Guest Posted August 3, 2007 Report Share Posted August 3, 2007 Is it correct that seven and five is thirteen or seven and five are thirteen? The 'or' implies that at least one is correct. As only once change has occurred we must assume that the correctness refers to the change. Link to comment Share on other sites More sharing options...
Guest Posted September 2, 2007 Report Share Posted September 2, 2007 In the question, it obviously amplifies the fact that the answer is concerning whether or not it is grammaticaly correct to say 'is' thirteen, or 'are' thirteen. So the answer is 'is', and the technicality of the real answer is unimportant. Link to comment Share on other sites More sharing options...

Guest Posted September 25, 2007 Report Share Posted September 25, 2007 Hi spazchik, There are 7 children standing in a row, each with a number/label (1 thru 7). Child 5 is thiteen years old, child 7 is also thirteen. So, 5 and 7 'are' thirteen. Link to comment Share on other sites More sharing options...
Guest Posted September 26, 2007 Report Share Posted September 26, 2007 I thought of it because of the joke "6 * 9 = 42", this joke is from The Hitchhiker's Guide to the Galaxy. It's performed in base-13. DARN, that thing has always puzzled me, and you tell me the obvious in so little words. I was always guessing someone made a translation error (I read it in Dutch), so I never thought of base-conversion. Thanx for beating some sense into me.

Guest Posted October 4, 2007 Report Share Posted October 4, 2007 well . . . I don't know about you but I'm pretty sure 7+5 does NOT equal 13. Link to comment Share on other sites More sharing options...

Guest Posted December 5, 2007 Report Share Posted December 5, 2007 Well, if we're getting down to the nitty gritty semantics of the question, everyone is wrong....7 AND 5 is 75 (or 57 to dyslexics). The word AND does not unequivocably mean a math expression Link to comment Share on other sites More sharing options...
Guest Posted December 5, 2007 Report Share Posted December 5, 2007 There is another one that i think works better when speaking. "Which is correct? The yolk of the egg are white or the yolk of the egg is white." Link to comment Share on other sites More sharing options...
Guest Posted December 9, 2007 Report Share Posted December 9, 2007 5+7=12.... So it wouldn't matter if you said "is" or "are" because neither are correct. Since Five and Seven don't add up to thirteen. [Just so you know] Link to comment Share on other sites More sharing options...
Guest Posted December 10, 2007 Report Share Posted December 10, 2007 Well if someone uses the 5 and 7 are 13 one could say 5 6/5 pies and 7 whole pies are 13 whole objects due to it never said anything about 5 and 7 what. Link to comment Share on other sites More sharing options...
Guest Posted December 19, 2007 Report Share Posted December 19, 2007 People, grammatically it is wrong, but mathematically it is right. If it was just a statement someone would make it should have been seven and five are thirteen, this would be the correct thing to do. But if one would say it as a mathematical expression it ought to be seven and five is thirteen (pronouncing 7+5=13), saying this doesn't make you wrong. Even this is right as I explained before, 7+5=13 (seven plus five equal thirteen, that statement has my preference when it comes to maths). 7+5=13 in base-9 as: 7*9^0 + 5*9^0 = 1*9^1 + 3*9^0 7*1 + 5*1 = 1*9 + 3*1 = 9 + 3 = 12 Voilá! Therefor both statements are most certainly correct! EDIT: @BoilingOil, you should wiki it sometime ... en de volgende keer het boek in het Engels lezen 6 * 9 = 42 (base-13) 6*13^0 * 9*13^0 = 4*13^1 + 2*13^0 6*1 * 9*1 = 4*13 + 2*1 6 * 9 = 52 + 2 6 * 9 = 54 (base-10 converted) Link to comment Share on other sites More sharing options...
Guest Posted February 21, 2008 Report Share Posted February 21, 2008 the answer is neither because seven plus five is twelve. and correct english is "seven and five is twelve." well, even if it isn't "correct," that is the colloquial way of saying it. why? because we say seven plus five IS twelve, so why would you say seven and five are twelve? it just sounds weird. it doesnt sound weird to say are.... there are two numbers so why wouldnt it be are?

Guest Posted February 29, 2008 Report Share Posted February 29, 2008 (edited) If the question were posed using the digits 13 then you might be able to use the base-9 'logic'.... However, the question was posed with the text 'thirteen'. The word thirteen is 13(base-10), period. if the text were 'one three, base nine'....then, ok.

Guest Posted March 9, 2008 Report Share Posted March 9, 2008 What is Correct - Back to the Logic Puzzles Is it correct that seven and five is thirteen or seven and five are thirteen? What is Correct - solution Of course, adding seven to five makes twelve and not thirteen. u got me i had think for second Link to comment Share on other sites More sharing options...
Guest Posted March 10, 2008 Report Share Posted March 10, 2008 I suppose it's also too late to point out that the digits '13' in base-9 are equal to twelve in base-10. The number system that Mythx is looking for is base-11. However, like you said, the nomenclature 'thirteen' is only meaningful in base-10, since it is a linguistic blend of three and ten (a number that by definition cannot exist in base-9). I do have to admit that it was a clever direction to go, though... It reminds me of the old computer joke: There are only 10 types of people in this world, those who understand binary and those who don't... If the question were posed using the digits 13 then you might be able to use the base-9 'logic'.... However, the question was posed with the text 'thirteen'. The word thirteen is 13(base-10), period. if the text were 'one three, base nine'....then, ok. Link to comment Share on other sites More sharing options...
Guest Posted March 18, 2008 Report Share Posted March 18, 2008 7+5=12 not 13. Also, as an answer to the is or are part of the question, it's are. This is of course if grammar still means s***. Link to comment Share on other sites More sharing options...

Guest Posted March 27, 2008 Report Share Posted March 27, 2008 Neither, 5 and 7 are TWELVE... learn to count. the way the question is worded it makes it a grammer question, in which case one of them is correct, if its a maths question then neither are correct.

Guest Posted March 27, 2008 Report Share Posted March 27, 2008 I don't see how there has been so much confusion and pointless discussion about this one. This is intended as a children's riddle/question. Would there be confusion if the question said "Is it correct that seven add five is thirteen OR that seven add five are thirteen?" It doesn't matter at all about the grammatical sentence because even if the grammar is incorrect the entire sense of the statements is false. Also the question does not imply that either statement is correct. "It is correct ..." at the start would imply this. Link to comment Share on other sites More sharing options...
Guest Posted March 27, 2008 Report Share Posted March 27, 2008 First of all, 7+5=12, not 13. In math, when spoken verbally, the correct grammar is "Seven and five is twelve because you are combining seven and five to make a single whole of twelve. Twelve is being used as a collective noun in this sense. Link to comment Share on other sites More sharing options...
