I hope someone could tell me about the details, or give me a link for the tutorial. Thx

Like this
To insert a code fragment you must put line, consisting of five twiddles: ~~~~~, before and after the code.
`~~~~~
for (int i = 1; i <= n; ++i) sum += i * i;
~~~~~ `
To use latex formulas, you must enclose in with dollar sign $\sum\limits_{i=1}^{n}{i^{2}}$
thanks a lot.
Could you tell how to force images?
= (n!)2
But... It is not (n!)^2 actually, because it is sum, not production :)
`~~~~~
for (int i = 1; i <= n; ++i) sum += i * i;
~~~~~ `
$$$\prod\limits_{i=1}^{n}{i^{2}}={(n!)}^{2}$$$
$$$\sum\limits_{i=1}^{n}{i^{2}}={2*{n^{2}}}$$$
$$$a_{n}-a_{n-1}$$$
i tryied above can be done by inclosing following inside "$" sign
\prod\limits_{i=1}^{n}{i^{2}}={(n!)}^{2}
\sum\limits_{i=1}^{n}{i^{2}}={2*{n^{2}}}
a_{n}-a_{n-1}
