Feedback:User/FloppyJoe/Calculator Command

World of Warcraft has a "/dump" command, which just does simple calculator tasks. I use a calculator all the time when playing, so I'd like to be able to use a calculator command in-game. All it really needs to have is the ability to do basic arithmetic tasks, such as multiply, divide, add and subtract. It'd also be nice to be able to put in multiple items and use parenthesis. i.e. (6*4)+5, etc. Thanks.
