**Proving a Boolean Theorem Using a Truth Table**

*Objective:* Demonstrate the Boolean theorem \( \overline{A} + (\overline{A} \cdot B) = \overline{A} \) using a truth table.

**Truth Table:**

| A | B | \(\overline{A}\) | \(B\) | \(\overline{A} \cdot B\) | \(\overline{A} + (\overline{A} \cdot B)\) |
|---|---|------------------|------|----------------------------|----------------------------------|
| 0 | 0 |                  |      |                            |                                  |
| 0 | 1 |                  |      |                            |                                  |
| 1 | 0 |                  |      |                            |                                  |
| 1 | 1 |                  |      |                            |                                  |

**Explanation:**

1. **Columns:**
   - **A, B:** The initial inputs.
   - **\(\overline{A}\):** The complement of A.
   - **\(B\):** B as it is.
   - **\(\overline{A} \cdot B\):** Result of \(\overline{A}\) AND B.
   - **\(\overline{A} + (\overline{A} \cdot B)\):** Result of OR operation between \(\overline{A}\) and \(\overline{A} \cdot B\).

Fill in each column using the values of A and B to verify the theorem.
