Nice quick one for the annoying little clever clogs amongst us... When do 7 and 2 make 31? | ||

base 10 mathematics involved? | ||

base 10 mathematics involved? nope  | ||

Nope because a different base is involved? Like binary? 7 = 111 = 3 ones, 2 = 10 = 1 one? Or nope because it's not really a math question? 7 = days in a week, 31 = days in a month? | ||

Nope because a different base is involved? yes Like binary? no... 7 = 111 = 3 ones, 2 = 10 = 1 one? ...but that is a fantastic reason, it's a pity to have to say it's not my answer. By all means, try another one | ||

Are all of the numbers given in the same base? Base 2? 3? 4? 5? 6? 7? 8? 9? 10? A? B? C? D? E? F? G? | ||

You shouldn't encourage me, or you'll end up with a lot of wild guesses If not all numbers are in the same base, then are: 7 and 2 in the same base? 7 and 31 in the same base? 2 and 31 in the same base? Are 7,2,31 in base 10 and we need to convert them to some other base(s) to find the answer? (If no, replace "base 10" with "base *", where * = some number, and repeat question.) Or, are 7,2,31 the result of converting some numbers x,y,z from base 10 to some other base(s)? (If no, replace "base 10" with "base *" and repeat question.) Or, are 7,2,31 themselves the bases of some numbers x,y,z which satisfy x+y=z? | ||

prime numbers relevant? though 7 is the fourth prime number. . . | ||

is "and" "times"? is "and" "plus"? Well: 7*2 = 14 ~ 31 base 13/3 7+2 = 9 ~ 31 base 8/3 | ||

Baskin and Robbins involved? ;-) | ||

Are all of the numbers given in the same base? Base 2? 3? 4? 5? 6? 7? 8? 9? 10? A? B? C? D? E? F? G? I don't know what the letters mean, by my source said base-16 - is that F? You shouldn't encourage me, or you'll end up with a lot of wild guesses darn... If not all numbers are in the same base, then are: 7 and 2 in the same base? 7 and 31 in the same base? 2 and 31 in the same base? all 3 numbers are in the same base as each other Are 7,2,31 in base 10 and we need to convert them to some other base(s) to find the answer? (If no, replace "base 10" with "base *", where * = some number, and repeat question.) no inter-basing is involved Or, are 7,2,31 the result of converting some numbers x,y,z from base 10 to some other base(s)? (If no, replace "base 10" with "base *" and repeat question.) applies here too - no inter-basing whatsoever Or, are 7,2,31 themselves the bases of some numbers x,y,z which satisfy x+y=z? good try, but no prime numbers relevant? though 7 is the fourth prime number. . . nope is "and" "times"? is "and" "plus"? neither of these the two numbers are manipulated in some fashion, but not in either of these ways Well: 7*2 = 14 ~ 31 base 13/3 7+2 = 9 ~ 31 base 8/3 i'll take your word for it - but unfortunately, any of this is irrelevant to the puzzle Baskin and Robbins involved? ;-) as much as I would love it to be, they are not  ;) | ||

Base 16 would be "G". Or, more properly, "10". Also, 7 ^ 2 = 31 in base 16. | ||

Good job! | ||

*CLAPS LOUDLY AND ENTHUSIASTICALLY* Well done, Mr. Morahan! ***** SPOILER ***** 7^2 (otherwise written as 7 x 7) does indeed equal 31. | ||

Nice one, Wunderland! |
