Checking -3:
-3|4376-27
 | -12-75207
 --------------------------------------
  425-69180


Since the last entry in the last row is NOT a 0, -3 is NOT a zero

================================================================

Checking 5:


5|4376-27
 | 202851455
 --------------------------------------
  4572911428


Since the last entry in the last row is NOT a 0, 5 is NOT a zero


================================================================

Checking -8:

-8|4376-27
 | -32-40272
 --------------------------------------
  45-34245


Since the last entry in the last row is NOT a 0, -8 is NOT a zero
================================================================

Checking 8:


8|4376-27
 | 325524464
 --------------------------------------
  4695584437


Since the last entry in the last row is NOT a 0, 8 is NOT a zero
================================================================

Checking -4:



-4|4376-27
 | -16-84312
 --------------------------------------
  421-78285


Since the last entry in the last row is NOT a 0, -4 is NOT a zero
