Introduction xi
This glossary provides definitions for important terms that are used throughout
this guidebook.
An argument is an input upon which the value of a function
depends.
A command is any entry submitted to the calculator using
ΒΈ. There are two types of TI-80 commands: instructions
and expressions.
An expression is a complete sequence of numbers, variables,
functions, and their arguments that can be evaluated to a
single answer. An expression returns the evaluated result to
ANS.
A function, which may have arguments, returns a value and
can be used in an expression.
A function is also the expression entered in the Y= editor used
in graphing.
The Home screen is the primary screen of the TI-80, where
expressions can be entered and evaluated and instructions
can be entered and executed.
An instruction, which may have arguments, initiates an action.
Instructions are not valid in expressions. An instruction does
not return a value to ANS.
A list is a set of values that the TI-80 can use for activities
such as evaluating a function at multiple values and entering
statistical data.
Menu items are shown on full-screen menus.
