I have a variable with specific skewness. How to correct the variable to have 0 skewness?

Let's say yourVariable = 10. Is that skewed? Can you give an example?
Are you talking about a stochastic variable that came, for example, from a Rayleigh distribution ( http://www.globalspec.com/reference/75467/203279/chapter-10-the-rayleigh-distribution) or log-normal distribution ( http://en.wikipedia.org/wiki/Log-normal_distribution) or something like that?

This is actually regarding the residuals that I got from a regression. Say this is res, when I computed skewness(res) it is 0.3. I want to create a new variable from res which is some kind of transformation of res to achieve 0 skewness. How to do that?
