NppCalc 0.6 Beta

NppCalc is a small, simple, easy to use Notepad++ add-in, specially designed to help you evaluate the expressions in your editor.

Basically while NppCalc is on the job all mathematical symbols in the expressions you write will be highlighted with the red color so that you can identify math expressions easily in a document.

To install it you just have to copy it in the plugins folder of your Notepad++ and you'll get a new entry in the designated menu of the editor.
