You would have to check for all 4^(6-1) combinations, since there are 4 possible operators and 6-1 positions at which operators can be plugged in! 
Is there any way to optimize this?

suppose Xi are the 6 int. and v the target value
the function is
F(X) = Sum(k=1..N){ v * (Prod(i=1..6 , i!=k) {(X-Xi)} /(Prod(i=1..6 , i!=k) {(Xk-Xi)}}
