add and subtract values

[dunebuggy]

Hello,
great job on 3.4!
Now i can build my whole house.
But there is one thing, i am missing: the possibility to add and subtract values (xy coordinates).
maybe you can add this feature in a future version.
greetings,
Gregor

Maybe... it wouldn't so difficult with JeksParser, the mathematical interpreter I wrote a few years ago. [;)]
