$aa_{22}^{33}$

$\hat{aa}$

$$aa_{22}^{33} + \hat{aa} +\dot{x}= \underbrace{abc} +\sum_{k=1}^n a_k$$
$$\begin{aligned} \dot{x} &=\sigma{y-x} \\ \dot{y} &=\rho x-y \\ \dot{z} &=-\beta z+xy \end{aligned}$$

$$\begin{aligned} \nabla \times \vec{\mathbf{B}} -\, \frac1c\, \frac{\partial\vec{\mathbf{E}}}{\partial t} & = \frac{4\pi}{c}\vec{\mathbf{j}} \\ \nabla \cdot \vec{\mathbf{E}} & = 4 \pi \rho \\ \nabla \times \vec{\mathbf{E}}\, +\, \frac1c\, \frac{\partial\vec{\mathbf{B}}}{\partial t} & = \vec{\mathbf{0}} \\ \nabla \cdot \vec{\mathbf{B}} & = 0 \end{aligned}$$
