Math Problem Statement

  1. Do the following arithmetic as if these were five-bit signed representations and indicate if overflow occurs and, if so, why. Note: Remember that you want to add. So, for signed subtraction, convert the subtrahend (the number being subtracted) to its 2's complement and add it.

    a. 10110 + 01101 b. 11001 + 00101 c. 10110 - 01101 d. 11111 - 01011
