The Calculator screen behaves exactly like any
other RPN-format calculator. It consists of a
stack that can contain any number of values and
buttons that perform various operations. When a

displayed in a special area called the active area.
This value is then place in Level 1 of the stack
after tapping the Enter key.
Tapping a button on the display performs the
corresponding operation on either the last value
in the display, or the last two values, depending
on the operation. Each button is explained below

×: Multiplies x and y.
6ZS: Swaps positions of x and y in the stack.
−: Subtracts y from x.
÷: Divides y by x.
'US: Drops (removes) x from the stack.
