Примерни формули: ${\displaystyle }$

\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 - $x\ge 1$

x\le 1 - $x\le 1$

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

x\neq 0 - $x\ne 0$

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

\triangle ABC \approx \triangle A_1B_1C_1 - $\mathrm{△}ABC\approx \mathrm{△}{A}_1{B}_1{C}_1$

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

\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}\sqrt{x_i+\frac{1}{\sqrt{x_i}+1}}}{\sqrt[x_{2007}]{\frac{1}{\sum_{cyclyc}a^{bc}}}}
