Perform binary addition using on such scheme

Check if the resulted addition is zero in decimal base.

# Question $2.$ In $8-$bit system, use two's complement scheme, please:

Represent $9_{10}$ in binary base $($base $2)$

Represent $-9_{10}$ in binary base $($base $2)$

Perform addition between two values in binary

Check the resulted addition to validate the result in decimal base $($base $10).$ Specifically,

convert the resulted addition to decimal base to validate.
