For example this is a Block level $$x = {-b \pm \sqrt{b^2-4ac} \over 2a}$$ formula, and this is an inline Level
$x = {-b \pm \sqrt{b^2-4ac} \over 2a}$ formula.

\\[ \frac{1}{\Bigl(\sqrt{\phi \sqrt{5}}-\phi\Bigr) e^{\frac25 \pi}} =
1+\frac{e^{-2\pi}} {1+\frac{e^{-4\pi}} {1+\frac{e^{-6\pi}}
{1+\frac{e^{-8\pi}} {1+\ldots} } } } \\]

Result

For example this is a Block level $x = {-b \pm \sqrt{b^2-4ac} \over 2a}$ formula, and this is an inline Level $x = {-b \pm \sqrt{b^2-4ac} \over 2a}$ formula.

\[ \frac{1}{\Bigl(\sqrt{\phi \sqrt{5}}-\phi\Bigr) e^{\frac25 \pi}} = 1+\frac{e^{-2\pi}} {1+\frac{e^{-4\pi}} {1+\frac{e^{-6\pi}} {1+\frac{e^{-8\pi}} {1+\ldots} } } } \]
