$\mathrm{Test\;of\;mathrm}$ I am also testing dollars signs: $x+3=5$ $5+3=x$ Testing dollar signs $x^2 + 3 = 4$

Testing multiple dollar signs: $r^2+2 = 7$ and then, $r^3-2 = 9$

$$$$ $x^2 + 3 = 4$

Dollar signs. $\dfrac{y}{r}=\sin \theta$ $\frac{m}{n}$ $cheesecake$ LaTeX didn't show up in the previews because the last } was missing.

$\frac{\sqrt{b^2-4aq}}{2\pi+3\pi+4\pi}$
