Homework Equations

The Attempt at a Solution
##FFFD_{16}## > (1's comp.) = ##0002_{16}## > (2's comp.) = ##0003_{16}##
##FFF1_{16}## > (1's comp.) = ##000E_{16}## > (2's comp.) = ##000F_{16}##
##0003_{16} * 000F_{16} = D2_{16} ##
But ##FFFD_{16} ## ( negative ) * ##FFF1_{16}## ( negative ) , so the answer should be positive .
The answer is ## = 0D2_{16}## (positive ) .
Could anyone check my answer please ?
