Phaelax,
Yep, that wasn't factorial, it was
logical not
Mr Handy, my answer for 8s is mathematically fine.
Refer to this table: http://www.rapidtables.com/math/symbols/Basic_Math_Symbols.htm
[root(8)] + [root(8)] + [root(8)] = 6
Square root of 8 is circa 2.8
Straight from the page:
[x] floor brackets rounds number to lower integer [4.3]= 4
So floor(2.8) is 2
floor might not be necessary, but it's not banned
As for my 0's and 9's, fair enough, although for a forum full of coders, it's understandable, right?
ie. (not 0 + not 0 + not 0) factorial
which in programming, comes to (1+1+1) factorial
oh, and if programming is allowed:
(!(!x)+!(!x)+!(!x))! = 6
where x<>0
EDIT: wow, all these not's and factorials are confusing
