write the following in Hindu-Arabic numeral.
CXL

Answer

To convert the Roman numeral CXL into Hindu-Arabic numeral, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Roman Numerals**: The Roman numeral given is CXL. We will break it down into its components:
- C = 100
- X = 10
- L = 50

2. **Understand the Order of the Numerals**: In Roman numerals, if a smaller numeral appears before a larger numeral, it is subtracted. In CXL, X (10) is before L (50).

3. **Perform the Subtraction**: Since X (10) is before L (50), we subtract:
- L (50) - X (10) = 50 - 10 = 40

4. **Add the Remaining Value**: Now, we add the value of C (100) to the result from the subtraction:
- C (100) + 40 = 100 + 40 = 140

5. **Final Result**: Therefore, the Hindu-Arabic numeral for CXL is 140.

### Final Answer:
CXL = 140
