Is there a way to quickly get the result of an expression in the Start > Run command input?

For example, if I wanted to get the result of (5+9)*79 I'd like to be able to press ⊞ Win + R, enter the expression and get the result.

Are there any lightweight utilities that can do this?

The Firefox search bar (with Google and search suggestions on) can do that. If you are already in Firefox, you can get to the search bar quickly with Ctrl+K. – William Jackson Jul 28 '11 at 11:33

Launchy has a bundled calcy plugin, which can do what you want.


There's also MathyResurrected plugin for more advanced calculations

I don't think you can do everything from the Run command window, but you could open a Command Prompt (cmd) from there and then execute the set command

set /a (5+9)*79 

Just did a search, you could pass everything to cmd and run this from the Run command window

cmd /k set /a (5+9)*79
