Some useful LaTeX code

Aligning and spacing

${\displaystyle {\begin{aligned}3+x&=4&&{\text{we are trying to solve for ))x\\[6pt]x&=4-3&&{\text{Subtract 3 from both sides))\\x&=1&&x{\text{ must be one))\end{aligned))}$

Boundaries of integration

Standard way:

${\displaystyle \int _{0}^{\infty }e^{-ax^{2))\,dx={\frac {1}{2)){\sqrt {\frac {\pi }{a))}\qquad {\text{and))\qquad \iiint _{\mathbb {R} ^{3))\langle \Psi |\Psi \rangle \,dx\,dy\,dz=1}$

Preferred way:

${\displaystyle \int \limits _{0}^{\infty }{\frac {\sin x}{x))dx={\frac {\pi }{2))\qquad {\text{and))\qquad \iiint \limits _{\mathbb {R} ^{3))e^{-a(x^{2}+y^{2}+z^{2})}\,dx\,dy\,dz=\left({\frac {\pi }{a))\right)^{3/2))$
