Answer

To determine whether the sentence "Mathematics is easy" is a statement, we need to analyze its characteristics based on the definition of a statement in mathematical reasoning.

### Step-by-Step Solution:

1. **Definition of a Statement**:
A statement is a declarative sentence that is either true or false, but not both. It must have a definite truth value.

2. **Analyze the Sentence**:
The sentence in question is "Mathematics is easy."

3. **Truth Value Assessment**:
- The truth value of this sentence can vary from person to person.
- For some individuals, mathematics may indeed be easy, while for others, it may be difficult.

4. **Conclusion**:
Since the truth of the sentence "Mathematics is easy" is subjective and can be true for some and false for others, it does not meet the criteria of a statement.

5. **Final Answer**:
Therefore, "Mathematics is easy" is **not a statement** because it does not have a definitive truth value that applies universally.
