topic. The built-in aplet types are
Function, Parametric, Polar,
Sequence, Solve, and Statistics. An
aplet can be filled with the data and
solutions for a specific problem. It is
reusable (like a program, but easier
to use) and it records all your settings
and definitions.
command An operation for use in programs.
Commands can store results in
variables, but do not display results.
Arguments are separated by semi-
colons, such as DISP
expression;line#.
expression A number, variable, or algebraic
expression (numbers plus functions)
that produces a value.
function An operation, possibly with
arguments, that returns a result. It
does not store results in variables. The
arguments must be enclosed in
parentheses and separated with
commas (or periods in Comma
mode), such as
CROSS

calculator. Go to HOME to do
calculations.
