Mathematik - LaTex Displaymath anomalies... and \displaystyle

Post subject: LaTex Displaymath anomalies... and \displaystyle

This does not work:
$\prod_{i=0}^{n}(i+n)$

while this does (note the two blank lines):
$\prod_{i=0}^{n}(i+n)$
In the next sample, the two blank lines do not work
$(n-k)! = \frac{\prod_{i=0}^{n-1}(n-i)}{\prod_{i=0}^{k-1}(n-i)}$

However, it turns out that this is the expected latex rendering. One can modify it with the \displaystyle override, done below:

$(n-k)! = \frac{\displaystyle\prod_{i=0}^{n-1}(n-i)}{\displaystyle\prod_{i=0}^{k-1}(n-i)}$

... and here the same as phpBB source:

[mm]
$$\prod_{i=0}^{n}(i+n)$$
[/mm]

while this does (note the two blank lines):
[mm]

$$\prod_{i=0}^{n}(i+n)$$
[/mm]
In the next sample, the two blank lines do not work
[mm]

$$(n-k)! = \frac{\prod_{i=0}^{n-1}(n-i)}{\prod_{i=0}^{k-1}(n-i)}$$
[/mm]
