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:

This does not work:
[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]

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

[mm]


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

And finally some references I found helpful while wrangling with the issue:
