This amazing calculator supplied to us by Hamad Belshalat,
allows the user to calculate normal arithmetic functions plus,
if you click on the edit button, you can enter equations, or,
if you prefer,
you can enter values for x and y in the numberpad
on the calculator, after the numbers 0 - 9.
All function keys are conveniently placed together
in the middle of the calculator pad.
The lower readout keeps memory values displayed
where you can see them.
