describes graphs. Chapter 9 describes how the TI

display a horizontally or vertically split screen to show
graphs and text simultaneously.
The home screen is the primary screen of the TI
.
83. On
this screen, enter instructions to execute and expressions
to evaluate. The answers are displayed on the same screen.
When text is displayed, the TI
.
83 screen can display a
maximum of eight lines with a maximum of 16 characters
per line. If all lines of the display are full, text scrolls off
the top of the display. If an expression on the home screen,

editor (Chapter 3), or the program editor
(Chapter 16) is longer than one line, it wraps to the
beginning of the next line. In numeric editors such as the
window screen (Chapter 3), a long expression scrolls to
the right and left.
When an entry is executed on the home screen, the answer
is displayed on the right side of the next line.
