Because the machine uses the complement code, the 32-bit int type commonly used in programming can be expressed in the range of [-231,231-1] Because the first digit represents the symbol bit. you can save one more minimum value when using the complement representation.

-digit binary number. If the current time is 6 points, I would like to set the time to 4 points, how to do it? We can:
1. Dial back 2 hours: 6-2 = 4
2.10 hours Forward: (6 +) MoD 12 = 4
3. Forward 10+12=22 Hours: (6+22) mod 12 =4
The MoD in the 2,3 method refers to the modulo operation, and the remainder of
minimum number. this is why the range of the 8-bit binary code expressed by the original code or the back code is [-127, + 127], and the range indicated by the complement code is [-128,127].
