The symbol I can be subtracted from ______.

Options

A. V only
B. X only
C. L only
D. Both V and X

Answer

To solve the question "The symbol I can be subtracted from ______," we need to understand what the Roman numeral "I" represents and which other Roman numerals can have "I" subtracted from them.

### Step-by-Step Solution:

1. **Identify the value of I**:
- The Roman numeral "I" represents the number 1.

2. **Identify the values of other Roman numerals**:
- V = 5
- X = 10
- L = 50

3. **Determine which numerals can have I subtracted from them**:
- Since I (1) is less than V (5), we can subtract I from V:
- 5 - 1 = 4 (which is represented as IV in Roman numerals).
- Since I (1) is also less than X (10), we can subtract I from X:
- 10 - 1 = 9 (which is represented as IX in Roman numerals).
- Since I (1) is also less than L (50), we can subtract I from L:
- 50 - 1 = 49 (which is represented as XLIX in Roman numerals).

4. **Evaluate the options**:
- The question provides options: V only, X only, L only, or both V and X.
- Since we can subtract I from V, X, and L, the correct choice is "both V and X."

5. **Final Answer**:
- The correct answer is "both V and X."
