Code Golf: All +-*/ Combinations for 3 integers

Answer 1

Javascript, 169 characters

(not counting unnecessary line breaks and indentation)

Edit: Now with input permutation

o=" ";i=i.split(o);z="+-*/";for(y=0;y<27;y++)for(x=0;x<16;x++){a=y/9|0;b=(y/3|0)%3;c=y%3;if(a!=b&&a!=c&&b!=c){s=i[a]+z[x/4|0]+i[b]+z[x%4]+i[c];o+=s+"="+~~(eval(s)+.5);}}

With indentation:

o=" ";
i=i.split(o);
z="+-*/";
for(y=0;y<27;y++)
for(x=0;x<16;x++)
{
    a=y/9|0;
    b=(y/3|0)%3;
    c=y%3;
    if(a!=b&&a!=c&&b!=c)
    {
        s=i[a]+z[x/4|0]+i[b]+z[x%4]+i[c];
        o+=s+"="+~~(eval(s)+.5);
    }
}
