If for any reason you need to uninstall mathematica, you should delete the files associated to it. If the installation was the usual one, follow the below steps.
[> cd /usr/local
[> sudo rm -r Wolfram
[> cd bin
[> sudo rm math* Math* mcc* Wolfram* wolfram*
[> cd /usr/share
[> sudo rm -r Mathematica
[> cd
[> rm -rf .Mathematica
This would be enough.
Enjoy!
