a) 10, 10, 4, 4 (easy)

b) 7, 7, 3, 3 (medium)

c) 8, 8, 3, 3 (not so easy)

anyone has similar puzzles to this?

edit: oh and every number has to be used seperatly...cant use "38" or so in c).

b - 7x3 +3

c - 8x3

Try 7, 7, 7, 7, 7, 7 to make 777 - 17 Jun '07 08:04

erm, i didnt mention (because i thought its clear) that of course you have to use ALL numbers.*Originally posted by doodinthemood***a - 10+10+4+4**

b - 7x3 +3

c - 8x3

Try 7, 7, 7, 7, 7, 7 to make 777

in b) one 7 is misssing, in c) 8 and 3 are missing.

and about a)....add the numbers again. is it really 24?
