 Let's take the number 5 for example (16-bit):
 ```
     0000 0000 0000 0101   # The two's complement (signed) value is  5, the unsigned value is 5
-    1111 1111 1111 1011   # The two's complement (signed) value is -5, the unsigned value is 65533
+    1111 1111 1111 1010   # The two's complement (signed) value is -5, the unsigned value is 65533

     The sign bit is set
