Base Five Subtraction
1. **State the problem:** Subtract the base five numbers $314_5$ and $233_5$.
2. **Recall the subtraction rules in base five:** In base five, digits range from 0 to 4. If a digit in the minuend is smaller than the corresponding digit in the subtrahend, we borrow 1 from the next higher place value, which equals 5 in the current place.
3. **Write the numbers aligned by place value:**
\begin{array}{c c c}
&3 & 1 & 4_5 \\
-&2 & 3 & 3_5 \\
\hline
\end{array}
4. **Subtract the rightmost digits:** $4 - 3 = 1$ (no borrowing needed).
5. **Subtract the middle digits:** $1 - 3$ is not possible without borrowing. Borrow 1 from the leftmost digit (3 becomes 2), and add 5 to the middle digit: $1 + 5 = 6$.
Now subtract: $6 - 3 = 3$.
6. **Subtract the leftmost digits:** After borrowing, leftmost digit is $2 - 2 = 0$.
7. **Combine the results:** The difference is $0 3 1_5$.
8. **Remove leading zeros:** The leading zero can be omitted, so the final answer is $31_5$.
**Final answer:** $314_5 - 233_5 = 31_5$.
