what about 25 - (25/25)? It works also.
but that way is using two seperate digits 2 and 5, whereas the teaser ask to use only a single digit, ei; any between 0 and 9. and then to use it only three times.
cool, i got the first 2!! didnt even think of using the sq root! great teaser!! i liked it!
I got 3^3-3. sweet .
clever. seen it, but i like it. if you can use multiple digits, there are quite a few answers
23 + (23/23)
14.0 + (140/14.0)
and tons of other ones. single digits are tough though. fun!
23 + (23/23)
14.0 + (140/14.0)

Didn't get the 9! And to think that 9 is my favorite number!

How about 4! + 4 - 4 = 24.
How about 4 x (4 + sqrt(4))
