The TI-84 Plus Silver Edition is a graphing calculator designed for a wide range of mathematical and scientific applications. It features a user-friendly interface with various keys and menus to facilitate data entry, expression editing, and graph plotting.

Function Description:

The TI-84 Plus Silver Edition serves as a versatile tool for students and professionals, enabling them to perform complex calculations, graph functions, analyze data, and solve equations. Its core functions include:

Basic and Advanced Calculations: Performing arithmetic operations, trigonometric functions, logarithms, and more complex mathematical computations.
Graphing Capabilities: Plotting various types of functions, including function (FUNC), parametric (PAR), polar (POL), and sequence (SEQ) graphs. It supports both connected and dot graph styles.
Equation Solving: Utilizing a built-in Solver feature to find solutions for equations.
Data Analysis: Supporting statistical diagnostics and data collection, especially when connected to external devices like a CBL 2™.
Programming: Allowing users to create and run programs, enhancing its functionality for specific tasks.
Communication and Transfer: Facilitating the transfer of programs, Apps, matrices, pictures, and even operating systems between two TI-84 Plus Silver Edition calculators or other compatible TI devices.

Important Technical Specifications:

Power Source: Requires four AAA batteries.
Memory: Features Constant Memory™, which retains all settings and memory contents even when the calculator is turned off.
Operating System: Compatible with the 2.53MP Operating System, which introduces new features like stacked fractions. Users can check their operating system version through the "1:About" option in the MEM menu.
Display: The screen contrast can be adjusted. A number in the top right corner indicates the contrast level, which can also serve as an indicator for low battery if it needs to be set to 7 or higher.
Connectivity: Equipped with a USB port (located on the top right edge) for connecting a USB Unit-to-Unit cable for data transfer. It also has an I/O port for communication with other TI products.

Usage Features:

Turning On/Off: The calculator is turned on by pressing the ON key. To turn it off, users press 2nd followed by OFF.
Automatic Power Down (APD): To conserve battery life, the calculator automatically turns off after approximately 5 minutes of inactivity. Pressing ON resumes work from where it was left off.
Key Functions:
- 2nd Key: Activates the secondary functions (blue text above keys) for the next keystroke. For example, 2nd then x-1 accesses the MATRIX menu.
- ALPHA Key: Activates the green letters (A-Z) above many keys and provides access to shortcut menus (F1-F4) and the Solver feature (ALPHA then SOLVE).
- ALPHA [A-LOCK]: Locks the calculator in alpha-lock mode for typing multiple letters in succession. Press ALPHA again to exit.
- ENTER Key: Executes instructions or expressions.
- 2nd [INS]: Changes the cursor to an underline (_) for inserting characters. Press direction arrows or 2nd [INS] again to exit insert mode.
Editing Features:
- Left/Right Arrow Keys (< / >): Move the cursor horizontally within an expression.
- Up/Down Arrow Keys (^ / v): Move the cursor through MathPrint™ expressions (e.g., stacked fractions) and access history.
- 2nd [<]: Moves the cursor to the beginning of an expression.
- 2nd [>]: Moves the cursor to the end of an expression.
Mode Settings: Accessed by pressing the MODE key. These settings control how numbers and graphs are displayed and interpreted.
- Navigation: Use ^ / v to move between setting lines and < / > to select options within a line. Press ENTER to confirm a selection.
- Key Settings Include:
  - NORMAL SCI ENG: Numeric notation.
  - FLOAT 0123456789: Number of decimal places to display. FLOAT shows all significant digits up to ten; numerical options lock in a specific number of decimal places.
  - RADIAN DEGREE: Unit of angle measure.
  - FUNC PAR POL SEQ: Graphing mode selection.
  - CONNECTED DOT: Graph plotting style.
  - SEQUENTIAL SIMUL: Graph plotting order (one at a time or simultaneously).
  - REAL a+bi re^θi: Complex number display format (real, rectangular, or polar).
  - FULL HORIZ G-T: Screen display mode (full screen or split-screen).
  - MATHPRINT CLASSIC: Display mode for mathematical expressions.
  - n/d Un/d: Fraction display format (improper or mixed).
  - ANSWERS: AUTO DEC FRAC: Format for answers (automatic, decimal, or fraction).
  - GOTO FORMAT GRAPH: NO YES: Accesses the graph format menu.
  - STAT DIAGNOSTICS: OFF ON: Toggles statistical diagnostics.
Linking Calculators:
- Connection: Use a USB Unit-to-Unit cable. Insert one end into the USB port of the sending calculator and the other end into the USB port of the receiving calculator.
- Sending/Receiving Process:
  1. On the receiving calculator, press 2nd [LINK], navigate to the RECEIVE menu, and press ENTER. "Waiting..." will appear.
  2. On the sending calculator, press 2nd [LINK] to access the SEND menu.
  3. Select the item type (e.g., 3:Pgrm... for programs).
  4. Use ^ / v to select the desired item (a solid square ■ indicates selection) and press ENTER.
  5. Navigate to the TRANSMIT menu and press ENTER to initiate the transfer.
- Conflict Resolution: If an item being sent already exists on the receiving calculator, options like Rename, Overwrite, Omit, or Quit will be presented.
- Multiple Items: Users can mark and send multiple items simultaneously.

Maintenance Features:

Battery Replacement: The manual advises replacing AAA batteries when the contrast level needs to be set to 7 or higher, or when a low battery message appears.
Constant Memory™: This feature ensures that all settings and memory contents are preserved, reducing the need for frequent reconfigurations after turning the calculator off.
