This is a Caclculator i build, and i just finished it!
I'm really happy about it, it works pretty good.
You have a number pad where you can select the numbers and + or - it and on the screen you can see your awnser.
I used some ideas that i have seen from other projects, because i really liked them.
So i hope you enjoy and have some fun with it.

Check out my Youtube channel and maybe give a like and a subscribe: www.youtube.com/user/FreakieFan

I allready uploaded my first redstone tutorial so be sure to check that out.
Thanks!
