Unit
2's complement
Binary numbers are generally used to represent negative numbers.
Negative numbers are expressed by "Inverting all bits of a positive number and adding 1 to the result".
(Example) "-1" is expressed as 2's complement
"-1" can be calculated by "0-1".
There are methods for simple calculation without performing this kind of computation.
For instance, "Negative number = inverting all bits of a positive number and then adding 1 to the result".
The first digit is used to judge whether the number is positive or negative.

calculations.
