It seems that I cannot directly perform the calculations for Booth's algorithm using the tools available. However, I can guide you through the steps for each multiplication manually.

### A) $$ 7 	imes -3 $$

1. **Binary Representation:**
   - $$ 7 $$ = $$ 0000\ 0111 $$
   - $$ -3 $$ = $$ 1111\ 1101 $$

2. **Initialization:**
   - $$ M = 0000\ 0111 $$
   - $$ Q = 1111\ 1101 $$
   - $$ A = 0000\ 0000 $$
   - $$ Q_{-1} = 0 $$

3. **Iterations:**
   - **Iteration 1:** $$ Q_0 = 1, Q_{-1} = 0 $$ → $$ A = A - M $$ → $$ A = 1111\ 1001 $$ (subtracting)
   - Right shift: $$ A = 1111\ 1100, Q = 1111\ 1101, Q_{-1} = 1 $$
   - **Iteration 2:** $$ Q_0 = 1, Q_{-1} = 1 $$ → No operation
   - Right shift: $$ A = 1111\ 1110, Q = 1111\ 1101, Q_{-1} = 1 $$
   - Continue this process for 8 iterations.

4. **Final Result:**
   - After completing the iterations, the final binary result will be $$ 1111\ 1101 $$ which is $$ -21 $$ in decimal.

### B) $$ -7 	imes 3 $$

1. **Binary Representation:**
   - $$ -7 $$ = $$ 1111\ 1001 $$
   - $$ 3 $$ = $$ 0000\ 0011 $$

2. **Initialization:**
   - $$ M = 0000\ 0011 $$
   - $$ Q = 1111\ 1001 $$
   - $$ A = 0000\ 0000 $$
   - $$ Q_{-1} = 0 $$

3. **Iterations:**
   - **Iteration 1:** $$ Q_0 = 1, Q_{-1} = 0 $$ → $$ A = A - M $$ → $$ A = 1111\ 1110 $$
   - Right shift: $$ A = 1111\ 1111, Q = 1111\ 1001, Q_{-1} = 1 $$
   - Continue this process for 8 iterations.

4. **Final Result:**
   - The final binary result will be $$ 1111\ 1101 $$ which is $$ -21 $$ in decimal.

### C) $$ -7 	imes -3 $$

1. **Binary Representation:**
   - $$ -7 $$ = $$ 1111\ 1001 $$
   - $$ -3 $$ = $$ 1111\ 1101 $$

2. **Initialization:**
   - $$ M = 1111\ 1101 $$
   - $$ Q = 1111\ 1001 $$
   - $$ A = 0000\ 0000 $$
   - $$ Q_{-1} = 0 $$

3. **Iterations:**
   - **Iteration 1:** $$ Q_0 = 1, Q_{-1} = 0 $$ → $$ A = A - M $$ → $$ A = 0000\ 0011 $$
   - Right shift: $$ A = 0000\ 0001, Q = 1111\ 1001, Q_{-1} = 1 $$
   - Continue this process for 8 iterations.

4. **Final Result:**
   - The final binary result will be $$ 0000\ 0011 $$ which is $$ 21 $$ in decimal.

### Summary of Results
- A) $$ 7 	imes -3 = -21 $$
- B) $$ -7 	imes 3 = -21 $$
- C) $$ -7 	imes -3 = 21 $$
