-               +Right away we can see that R = 1 since RCREPB x R = RCREPB, N ext we can also see that C must = 0 since P - P = C and B - B = C with no borrowing taking place so C = 0 
 + 
 +Now we can look at C - H = H where C must be borrowing so in base 8 it is (0 + 10) - H = H so that means H = 4 
 + 
 +Next knowing this we can look at H - C = V where H must be being borrowed by B meaning B << V and that V < H so V = 3 and B must = 2 
 + 
 +Now we can look at P - H = R where we know P is being borrowed from so it is really (P - 1) - 4 = 1 so P = 6 
 + 
 +Knowing this we can look at V - E = P where we know that V is borrowing so in base 8 it is (3 + 10) - E = 6 so therefor E = 5 which leaves Z to = 7 
 + 
 +So we have 
 + 
 +0 = C 
 + 
 +1 = R 
 + 
 +2 = B 
 + 
 +3 = V 
 + 
 +4 = H 
 + 
 +5 = E 
 + 
 +6 = P 
 + 
 +7 = Z 
 + 
 +We verify the values by plugging in the numbers
