Примерни формули:

\frac{1}{2} - ${\frac {1}{2}}$

\frac{1}{1+\frac{1}{1+\frac{1}{2}}} - ${\frac {1}{1+{\frac {1}{1+{\frac {1}{2}}}}}}$

\sqrt{2} - ${\sqrt {2}}$

\sqrt[3]{2} - ${\sqrt[{3}]{2}}$

x\ge 1 - $x\geq 1$

x\le 1 - $x\leq 1$

1\le x\le \pi - $1\leq x\leq \pi$

x\neq 0 - $x\neq 0$

x_1\ge x_2\ge x_{2007}\ge x_{2007}^n\ge x_{2008}^{n+1} - $x_{1}\geq x_{2}\geq x_{2007}\geq x_{2007}^{n}\geq x_{2008}^{n+1}$

\triangle ABC \approx \triangle A_1B_1C_1 - $\triangle ABC\approx \triangle A_{1}B_{1}C_{1}$

\sum_{cyclyc} ab = ab+bc+ca - $\sum _{cyclyc}ab=ab+bc+ca$

\sum_{cyclyc}\frac{a}{bc} = \frac{a}{bc}+\frac{b}{ca}+\frac{c}{ab} - $\sum _{cyclyc}{\frac {a}{bc}}={\frac {a}{bc}}+{\frac {b}{ca}}+{\frac {c}{ab}}$

\sum_{i=1}^{\infty}\frac{1}{x_i} = \frac{\pi^2}{10} - $\sum _{i=1}^{\infty }{\frac {1}{x_{i}}}={\frac {\pi ^{2}}{10}}$

\frac{\sum_{i=1}^{n}\sqrt{x_i+\frac{1}{\sqrt{x_i}+1}}}{\sqrt[x_{2007}]{\frac{1}{\sum_{cyclyc}a^{bc}}} - Failed to parse (syntax error): {\displaystyle \frac{\sum_{i=1}^{n}}}
