<h1>Mathematical Formulas Containing % Symbol</h1>

<h2>1. LaTeX Format Examples</h2>

<h3>Inline LaTeX formulas:</h3>
<p>The percentage increase is calculated as $\frac{new - old}{old} \times 100\%$.</p>

<h3>Display LaTeX formulas:</h3>
<p>Compound interest formula:</p>
$$A = P\left(1 + \frac{r\%}{n}\right)^{nt}$$
