# Math Syntax Test

## Inline Math

Inline: $E = mc^2$
Another: $\sum\_{i=1}^{n} i$
Complex: $\int\_0^\infty e^{-x^2} dx = \frac{\sqrt{\pi}}{2}$

## Block Math

$$
E = mc^2
$$

$$
\sum\_{i=1}^{n} i = \frac{n(n+1)}{2}
$$

$$
\begin{aligned}
a &= b + c \\
d &= e + f
\end{aligned}
$$

## Unclosed Math

$unclosed inline

$$
unclosed block

$$ also unclosed

## Dollar Signs (Not Math)

Price: $100
Range: $50 - $100
Currency: $USD

## Mixed Valid and Invalid

Valid: $x^2$
Invalid: $
Also invalid: $$
Back to valid: $y = mx + b$

## LaTeX Commands

$\alpha \beta \gamma$
$\frac{1}{2}$
