Is there any Software to calculate Ohms Law and other electronics math?

You would be better off with a piece of log/log graph paper, labeled for a
convenient range of V on one axis, and I on the other axis. Every
resistor value can be represented by a straight line (a diagonal)
on the graph. Scribe in 1 ohm, 10, 100, 1000, 10k etc. lines, and glance
at it when you want a value.

Calculators are slow. Laminated charts inform in a couple of seconds, and
can be taped on any convenient door/partition/refrigerator.

And there must be a PDF or XLS etc file that generates log/log charts
for printing out locally.

Which reminds me that decades ago I wrote a spreadsheet to display the
Fourier synthesis of a square wave from the first half-dozen harmonics.
Must have it somewhere...
