For engineers and such, the new calculator could be pretty nice for all
the scientific functions...but for most folks the classic calculator
from those very ancient days of Win8.1 is probably just fine.

Few here under 100 years of age have probably even heard of Windows 8.1
, so thanks for those wonderful memories of times now past.

BTW: I guess Windows 7 must have done calculations using Roman numerals.

I think I might have written a Roman Numeral -- Decimal converter a
long time ago, just for fun (fun?).

It was not trivial, but not hugely difficult either, IIRC.

I'd say this: if you want to create a calculator to do arithmetic in
Roman numerals, I'd advise using my converter to convert to decimal
first, then do the calculations, then convert back :-)

Sadly, I have no idea where the program might be today. Probably in a
landfill somewhere.

But I just looked at the Android app store, Google Play. No shortage of
Roman Numeral converters if you want one, & many are free.

Here's my first hit:

Also, here's a calculator that I found:

I just copied the links - I made no attempt to look at the sites :-)




Thanks for the great info. I once saw a short movie about performing
calculations with Roman Numerals...it was near impossible

That's why they used abacuses.

The weird thing is how close an abacus is to Arabic numerals (by which I
mean any kind of positional notation), yet no one west of India made
that leap until Arab mathematicians eventually learned about them and
passed them on to the West.

I have seen references to algorithms for arithmetic in Arabic numerals,
or even (IIRC) descriptions, but sadly, no movies. I'd guess they're not
for the faint of heart :-)

I just looked at YouTube. Didn't find much, but one explication of
multiplication was too complicated, i.e, it was probably correct :-)

I you're interested in mathematics on Youtube, I hope you've found
"numberphile", "computerphile" and "vihart". They'll lead you to
others (or into insanity, one or the other).
