Using the four digits 3,3,7,7 and the mathematical operators +,-,*,/ write an expression equal to 24. You must use each digit exactly once, but may use each operator multiple times, or not at all. Parentheses are allowed. The following would be a valid expression:
(7 + 3)/(7 + 3) = 1 (NOT THE ANSWER)
chib can't answer this (if he shows up) because he has already done so the last time I posed this riddle.
still trying...got to 23 and 25...but 24???? like it....
Alexandra
Chib was such a butt when he solved this, he said it's a good head riddle (no pen and paper). LOL
Looks like I got a new riddle buddy!
You got it!!! Such a shame it's already 2 am here and I am a working lady....hope that nobody will try to solve this before I do!!!!
Alexandra
They will try. I'm betting you'll get it.
Prodigal son is working on it, too.....And it's driving him nuts!
That, is a good sign! Means the riddle is tricky enough.
Chib said he had a bit of difficulty getting one of the 7s in. That is actually a huge hint.
Well, what direction have you been going in? I can try to help if I see taht you are going in the wrong direction somewhere.
(7*3)+3=24.....but have one 7 left over, ((7+3)*3-7)+3=24-but need one more digit 3.....
also have variations of getting 23 or 25....but no way to get 24...
((7+3)*3)-7=23
(7+7)+(3*3)=23 etc.
((7*3)-3)+7=25
((7-3)*7)-3=25......uh huh......grrrrrrrr.....I just hate it....
Alexandra
ps. Also tryed to play with numbers without operators....but that doesn't help either
Alexandra, I've been trying to end up with a product of 8 that then gets multiplied by 3 (i.e, using 7,7, and 3 to wind up with 8.) Not working.
Can we use decimals? Like, .7 + .3?
Ok, BIG hint. You need to divide. No decimals.
Can we squash 'em together? Like 77?
And if I dream tonight about those 3,3,7,7 digits, it will be your fault, Craven.
See you when I find the solution,
Alexandra
I've got the answer!
Doyou want me to post it or just PM it to Craven so you all can continue?
, tell me something more....I know all about that one 7, but ....uh huh, I love math, and hate when have something in front of me that I can't solve..
