cube root, sure its own mathematical operator, but it represents x^(1/3)?*Originally posted by talzamir***3! / cubic root of 8 x 8 = 6 / 2 x 8 = 3 x 8 = 24 seems perfectly valid to me? Where's the one?**

Using Excel, it's simply ROUND(8*3,(3/8))*Originally posted by Silverstriker***Using only 3,3,8 and 8**

You have to use all four numbers - you can use any mathematical symbol that you wish. There are at least four ways of solving the puzzle

3/8 can be 8/3, 3+8, 83, etc. Same result.

you are right, in 1st one factorial is not alright and using 38 as number isn't either. you can use only 3 and 8 separated.*Originally posted by talzamir***only brackets and +-x/ .. hmm..**

38 - 8 - 3! = 30 - 6 = 24; this is not acceptable, then as factorial is out?

3 / .3 + 7 + 7 = 10 + 7 + 7 = 24; is this okay, (ab)using a decimal point?

in 2nd you are right about not using decimals.
