Electronic – How to build a calculator


I'm a newbie in electronics. I'm trying to build a calculator from scratch as a simple project and side hobby to keep me busy.

My goal is to build a simple calculator, not a scientific or graphing calculator, although I don't mind receiving information about how to do that either, just for kicks.

Is there a good tutorial for this? How should I start?

Here is an example of a calculator that you can build without too much electronics knowledge. It's full featured, although addition is not included.

Yes I'm joking, don't take this too seriously
