1. Using 4 bits and two's complement representation, what is the binary representation of the following signed decimal values:

(A) +6 

(B) -3

2. Perform the following 5-bit binary addition showing the carry bit that propagates to each column. Assume the numbers are unsigned binary quantities:

01110

+ 01011

3. What does the 3-character string "X+Y" look like internally using the 8-bit ASCII code?(Go to www.unicode.org to find the specific code mappings for these three characters.)

4. Using 10 bits to represent the mantissa (sign/magnitude) and 6 bits for the exponent (also sign/magnitude), show the internal representation of the following two values:

(A) +0.25

(B) -32 1/16

5. Explain exactly what happens when you add a 1 to the following 5-bit, two's complement value: 01111
