It's an eeeevil riddle, it took me forever to solve it (cutting down vegetables for 2 big salads for all the guests on the holiday, plus most of washing the dishes afterwards): to construct the umber 21 out of 1, 5, 6 and 7. All four of addition, subtraction, multiplication, and division operations are allowed, and only them. Each number must be used in the calculations exactly once.
Hmm. Tricky. I've found a bunch of different ways to get 22, but not 21. I'm trying to see if there's a systematic way to do this, or if it's just trying a bunch of different stuff.
Hil! Is your schedule this month all crazy because of the holidays?

I tried to sort of work backwards, to see which numbers I'd need and then try to create them from the combinations of the others. I didn't manage to be more methodical than that.

Yep. Pretty much everything has been on a day when I had something to do (the one exception was the second day of Rosh Hashanah), so I've been scrambling to catch up lately.

Yeah, that's what I've been doing. Nothing's worked quite yet. Everything I've tried has two 1s in it. I'm trying to figure out how to fix that.

I checked a brain food site to get a hint, but they have "make 1 out of 1,5,6,7". I didn't see a 21 and they had like 100 pf these problems listed.
I've solved the puzzel, (whitefonted) except I did it in a weird way. The way I did it is not prohibited by the rules, so I say I win.
Someone tell me if there's another way to solve it: It's easy if you assume the numbers are in base eight. Is that cheating?
eta to whitefont more....
t backs slowly away from tommy and the puzzle.
Dear print designer:
Your designs rock. Your grasp on InDesign leaves a ton to be desired.
Signed, someone who is spending the afternoon slapping bookmarks into a PDF because you don't know SQUAT about styles in InDesign.

I can't imagine how hard it is when the 'everyday' schedule doesn't accomodate for holidays.
Is that cheating?
Yup.
