To see how any formula was written in any question or answer, including this one, right-click on the expression and choose "Show Math As > TeX Commands". (When you do this, the '$' will not display. Make sure you add these: see the next point. There are also other ways to view the code for the formula or the whole post.)

**For inline formulas, enclose the formula in $…$. For displayed formulas, use $$…$$.**

These render differently. For example, type

$\sum_{i=0}^n i^2 = \frac{(n^2+n)(2n+1)}{6}$

to show ∑ni=0i2=(n2+n)(2n+1)6 (which is inline mode) or type

$$\sum_{i=0}^n i^2 = \frac{(n^2+n)(2n+1)}{6}$$

to shown∑i=0i2=(n2+n)(2n+1)6(which is display mode).
