c) Given the following signed decimal numbers, represent them in the sign- magnitude, 1's complement and 2's complement systems: 24.-55. (6 points) d) Given two numbers in the 1's complement system: A = 11010, B = 01101, find A - B. Check for overflow. If there is no overflow, explain why. If there is, fix it and show the correct computation. (4 points) e) Given two numbers in the 2's complement system: A = 01011, B = 110, find A + B. Check for overflow. If there is no overflow, explain why. If there is, fix it and show the correct computation. (4 points) HINT: B must be represented in 5 bits
