Adding 1 to -127 in Byte: Understanding the Result

The result of -127 + 1 is -126. This might seem counterintuitive, but it's a result of how negative numbers are represented in computers using two's complement notation.

In a byte, which has 8 bits, the most significant bit (MSB) indicates the sign. When adding 1 to -127, the result is effectively a wrap-around from the lowest negative value (-128) to the highest positive value (127).
