• $\int_a^x f(\alpha\,)\,dx$
• $\int_1^\infin \frac{1}{k}\,dk$
• $\sqrt{x^2+2x+1}=|x+1| - \left(\left(\frac{2x^2}{x}\right)^2\right)^2$
• $\sqrt{\sqrt{\sqrt{x}}}$
• $\ E = \sum_{i=1}^N e^{- J_{ij} \sigma_i \sigma_j}$
• $\left( \begin{smallmatrix} a&b \\ c&d \end{smallmatrix} \right)$
• $\therefore$
