Part B - Practicing unsigned subtraction
In the PartA introduction, overfiow is the "normal" case. Suppose we look at the problem in reverse:
-12
±4
-3
13
A negative overflow occurs since there are no negative numbers in unsigned arithmetic.
For each 8-bit subtraction problem, determine the difference and whether or not negative overfiow has occurred.
1. 85 - 124 =
2. Did negative overfiow occur?
(Y or N).
3. Ox5d - Oxa7 =
4. Did negative overflow occur?_ Y or N).
Enter your answers for questions 1-4 in order, with each answer separated by a comma. Question 1 should be an integer, question 3 should be a hex number (include 0x), and questions 2 and 4 should
be either a "y" or "N".
