Calculators in 2018
===================

I  used the  Elektronika MK-52  for most  of time.  I also  got a  nice
solar-powered  Sharp calculator  but it  is for  the case  when someone
wants to  borrow a calculator from  me (for some reason  people dislike
the RPN notation which is used by the MK-52).

I also  used my  new Numworks  [1] calculator  but not  much (I  can be
programmed in  Python but I dit  very little in this  direction; I only
used its ability to work with very compulicated formulas).

No other device I used for real work, I think.
