1. A right circular shift of 3 bits on a string of 8 bits is equivalent to a left circular shift of how many bits?

2. What bit pattern represents the sum of 01101010 and 11001100 if the patterns represent values stored in two’s complement notation? What if the patterns represent values stored in the floating-point format discussed in Chapter 1?

3. Using the machine language of Appendix C, write a program that places a 1 in the most significant bit of the memory cell whose address is A7 without modifying the remaining bits in the cell.
