Calculate expressions from Run command window

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?

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
