平方和公式百度百科
“平方和公式”在数学中通常指的是自然数的平方和公式，即：
$$
1^2 + 2^2 + 3^2 + \\cdots + n^2 = \\frac{n(n+1)(2n+1)}{6}
$$
这个公式可以用于快速计算前 $ n $ 个自然数的平方和。

公式说明：
- 左边：表示从 1 到 $ n $ 的所有自然数的平方之和。
- 右边：是一个代数表达式，可以直接计算出这个和。

举例：
比如当 $ n = 3 $ 时：
$$
1^2 + 2^2 + 3^2 = 1 + 4 + 9 = 14
$$
使用公式计算：
$$
\\frac{3(3+1)(2 \\times 3 + 1)}{6} = \\frac{3 \\times 4 \\times 7}{6} = \\frac{84}{6} = 14
$$
结果一致。
