Is it possible to do calculation in Unity interface?

Question

Is it possible to do maths in unity interface, after hitting the Alt key ?

Answer 1

I don't know if you can do it in the HUD (Alt-button), but you can do it in the Dash (super-button) with a scope.

Use these commands to install the Calculator Scope for Unity via terminal:

sudo add-apt-repository ppa:scopes-packagers/ppa
sudo apt-get update
sudo apt-get install unity-scope-calculator

Here the OMGUbuntu article on unity-scope-calculator.
