Ye, overlooked that back slash:confused:

Of course it works:
$\displaystyle \therefore$
$\displaystyle \because$

How do you type in %? My webbrowser didn't wanna display the page when I created a LaTeX formula with % in it as always when something in the LaTeX code is wrong.

$$\%$$ gives $\displaystyle \%$

Typing $$\sum_{i\ =\ 0}^n f(i)$$ gives $\displaystyle \sum_{i\ =\ 0}^n f(i)$, a Sigma sign as a sum sign. But how do you do if you want to have a multiplication sign, a Pi sign ($\displaystyle \Pi$) that works like the sum sign?

Is it possible to put a big cross all over the formula to make clear it is not true?

just say "not equal to"

Such as typing in $$1\neq-1$$ gives $\displaystyle 1\neq-1$

Can you make some part of the expression appear in another color?

Problems with \left and \right:

$\displaystyle \left(\frac{x}{y}\right)$
$\displaystyle \left[\frac{x}{y}\right]$
$\displaystyle \left|\frac{x}{y}\right|$
But $$\left{\frac{x}{y}\right}$$ doesn't work.

But:

$$\left\{ \frac{x}{y}\right\}$$

$\displaystyle \left\{ \frac{x}{y}\right\}$

does.
