Best calculator for the working engineer

[Csaba Tizedes]

Sorry guys and thank you for your patience - I hope nobody is disappointed in me.
According to Voldemar's unbelief, I collected some examples.
Later I think that it is useful and more clear if I write down the full story of this solver.

The link for the doc:

You must to know, English is not my native and I have no any knowledge about grammar...

I'm waiting for the valuable feedbacks - because this is really a homebrew solver by/for myself.
