Assume Ox3E is in two's complement sign-and-magnitude form (10 pts) a. Is it a positive or a negative number (1pt)? b. If in part A you conclude it is a negative number, convert it to its positive form. Conversely, if you conclude it is a positive number, convert it to its negative form (3pts). C. What is its magnitude in decimal notation (3 pts)? d. What is its magnitude in BCD notation (3 pts)? If you could not solve part C, assume a decimal magnitude of 43.
