I make a problem in polygon, that contains a math formula.
In preview, the formula appears normally. But in mashup contest, the formula do not show.
Anyone know why?

I dont know about formula, but the Output should be $$$C_k^n$$$ not $$$C_n^k$$$ Looking at the sample.
Edit: It is not, my bad.
As it was taught to me, in this notation: $$$\binom{n}{k}$$$ $$$n$$$ is above, but in $$$C^k_n$$$ $$$n$$$ is below. But I know $$$C^n_k$$$ is also used. So don't act so confident.
Choose English instead of Vietnamese, that may help
