**Question:**

21. Determine what is wrong with the following addition problem.

\[
  \begin{array}{c@{}c@{}c}
    & 2 & 3_{\text{six}} \\
  + & 4 & 3_{\text{six}} \\
  \hline
    & 6 & 6_{\text{six}} \\
  \end{array}
\]

**Explanation:**

This problem involves adding two numbers in base six and checking if the result is correct. The numbers being added are \(23_{\text{six}}\) and \(43_{\text{six}}\).

**Steps for Addition in Base Six:**

1. **Align the Numbers Vertically:**
   - Align the numbers \(23_{\text{six}}\) and \(43_{\text{six}}\) with the ones place lined up.

2. **Add the Digits from Right to Left:**
   - **Units/Ones Place:** Add \(3 + 3 = 6\).
     - In base six, the digit 6 does not exist. It should be converted, resulting in \(10_{\text{six}}\). This means you write down 0 and carry over 1.
   
   - **Tens Place:** Add \(2 + 4 = 6\), and don’t forget to include the carried over 1, totaling 7.
     - Again, in base six, 7 does not exist, so this translates to \(11_{\text{six}}\). You write down 1 and carry over 1.

3. **Double-Check the Result:**
   - After adjusting for carries, the solution should be \(110_{\text{six}}\), not \(66_{\text{six}}\) as stated.

**Error:**

The original calculation displayed an incorrect result. The proper addition process in base six reveals that the correct answer should be \(110_{\text{six}}\).
