  return (
    <button className="bg-blue-500 text-white px-4 py-2 rounded">
      {children}
    </button>
  );
};
```

```python
def fibonacci(n):
    if n <= 1:
        return n
    return fibonacci(n-1) + fibonacci(n-2)

### 1. Simple (Inline & Block)
Newton's second law is $F=ma$.
The mass-energy equivalence:
$$ E = mc^2 $$

### 2. Medium (Integrals & Fractions)
The Gaussian Integral:
$$
\int_{-\infty}^\infty e^{-x^2}dx = \sqrt{\pi}
$$

### 3. Complex (Limits & Summation)
Definition of Derivative:
$$
\frac{\partial f}{\partial x} = \lim_{h \to 0} \frac{f(x+h) - f(x)}{h}
$$

Sum of Squares:
$$
\sum_{i=1}^{n} i^2 = \frac{n(n+1)(2n+1)}{6}
