Mathematical Formula Editor (TeX in HTML) At the left \Left write TeX between$$ symbols:

$\sqrt{\frac{1.68 \times 10^9} {4.2 \times 10^{-4}}} = \sqrt{\frac{168 \times 10^7}{42 \times 10^{-5}}} = \sqrt{\frac{2 \times 2 \times 2 \times 3 \times 7} {2 \times 3 \times 7} \cdot \frac{10^7}{10^{-5}}}$

$= \sqrt{\frac{2 \times 2 \times \strike{ 2 \times 3 \times 7}} {\strike{2 \times 3 \times 7}} \times 10^{7 - (-5)}} = \sqrt{4 \times 10^{12}} = 2 \times 10^6$

Outside $$signs it's just HTML; double$$ for a dollar-sign. More examples:

$f(x) = \smashmargin2{\int\nolimits_{x}}^{\infty} \quad\frac{1}{z^2}{\quad}dz$, ${\angle}ABC = 60^\circ$, and $\bar{xy} = 2.3\hspace{5}\text{cm}$
