An alternative, extended calculator(software),
originally developed by my grandson Niklas
Burggraaff at 10 years of age (!).
It is suitable for a long sequence of calculations
as necessary in large equations.
It has two input options (X and Y) and it can
perform transformations of X and Y before doing the
operations with X and Y.
The results (Z) can be moved to X or Y to continue
the next sequence of transformations and operations,
or they can
be stored in S for later use in X or Y.
The record of actions is shown in a tracking
table.
In the example below, first the value 4 was
entered for X, next the square root of X=4 was taken
(resulting in 2),
then the the value 3 was entered for Y whereupon the
square of Y=3 was taken (resulting in 9),
and finally X and Y were
added to result in 11.

calculator in elementary mode and Ystatus:
