To convert the Roman numeral CDXCIV into a Hindu-Arabic numeral, follow these steps:

### Step-by-Step Solution:

1. **Identify the Roman Numerals**: The Roman numeral given is CDXCIV. We will break it down into its components:
- CD
- XC
- IV

2. **Convert Each Component**:
- **CD**:
- C = 100
- D = 500
- Since C is before D, we subtract: 500 - 100 = 400
- **XC**:
- X = 10
- C = 100
- Since X is before C, we subtract: 100 - 10 = 90
- **IV**:
- I = 1
- V = 5
- Since I is before V, we subtract: 5 - 1 = 4

3. **Add the Values Together**:
- Now, we add the values we calculated:
- CD = 400
- XC = 90
- IV = 4
- Therefore, the total is:
- 400 + 90 + 4 = 494

4. **Final Result**: The Hindu-Arabic numeral for CDXCIV is **494**.
