Hello, please help me solve this problem. Write clearly, and thank you!

**Problem 1: Sum of Squares Formula**

**Objective:** Prove that for all \( n \in \mathbb{N} \),

\[
0^2 + 1^2 + 2^2 + \cdots + n^2 = \frac{n(n+1)(2n+1)}{6}
\]

**Explanation:**

- This formula represents the sum of the squares of the first \( n \) natural numbers.
- The expression on the right-hand side is a well-known formula that can be derived using mathematical induction or other methods.
- The right side, \(\frac{n(n+1)(2n+1)}{6}\), represents the closed-form expression for the summation.

This equation is a fundamental result in elementary number theory and discrete mathematics, and it is often used in problems related to series and sequences.
