Using a TI-84 Plus Silver Edition Menu
You can access most TI-84 Plus Silver Edition operations using menus. When you press a key or key combination to display a menu, one or more menu names appear on the top line of the screen.
■The menu name on the left side of the top line is highlighted.
Up to seven items in that menu are displayed, beginning with item 1, which is also highlighted.
■A number or letter identifies each menu item’s place in the menu. The order is 1 through 9, then 0, then A, B, C, and so on.
■When the menu continues beyond the displayed items, a down arrow (
) replaces the colon next to the last displayed item.
■When a menu item ends in an ellipsis (...), selecting the item will display a secondary menu or editor.
Displaying a Menu
While using your TI-84 Plus Silver Edition, you will o
need to access items from its menus. When you pre
a key that displays a menu, that menu temporarily replaces the screen where you are working.
Example: Calculate 5 + 93
1. 5 + 9 Enter the expression in the home screen 2. Press ç
3.Press 3 to choose the correct item from the menu
4.Press Õto calculate

Moving Between Menus
Some of the keys on your TI-84 Plus Silver Edition access more than one menu. When you press such a key, the names of all accessible menus are displayed on the top line. When you highlight a menu name, the items in that menu are displayed. Press ~and |to highlight each menu name.
Setting Modes
Mode settings control how your TI-84 Plus Silver Edition displays and interprets numbers and graphs. Mode settings are retained by the Constant Memory™ feature when you turn off your TI-84 Plus Silver Edition. All numbers, including elements of matrices and lists, are displayed according to the current mode settings.

TI-84 Plus Silver Edition Expressions, Menus, and Graphing
Entering Expressions and Instructions
What is an Expression?
An expression is a group of numbers, variables, or functions and their arguments, or a combination of these elements. An expression
evaluates to a single answer. For example,( 13 )2 is an expression. On the TI-84 Plus Silver Edition, you enter an expression in the same order as you would write it on paper. You can enter an
expression on the home screen to calculate an answer.
Entering an Expression
To create an expression, you enter numbers, variables, and functions from the keyboard and menus on your TI-84 Plus Silver Edition. An expression is completed when you press Õ, regardless of the cursor location. The entire expression is evaluated according to Equation Operating System (EOS™) rules (see General Math page), and the answer is displayed. When an entry is
executed on the home screen, the answer is displayed on the right side of the next line.
The mode settings control the way the TI-84 Plus Silver Edition interprets expressions and displays answers. If an answer, such as a list or matrix, is too long to display entirely on one line, an
ellipsis (...) is displayed to the right or left. Press ~or |to display the rest of the answer.
