+# TI Programs
+
+A collection of various programs for TI calculators. Programs are written in TI-BASIC, and are in `.8xp` and `.txt` formats.
+
+## Programs
+
+To easily browse and download programs check out the website: [TI Programs](https://ti-programs.cqb13.dev/)
+
+## Contributing
+
+If you would like to add a program, please follow the guidelines below:
+
+1. Fork this repository.
+2. Create a folder in the `programs` directory with your GitHub username.
+3. Create a folder in your directory with the lowercase name of your program.
+4. Add your program in both `.8xp` and `.txt` formats.
+   - If you do not have a `.txt` version of your program, you can use [TI-Tools](https://github.com/cqb13/ti-tools) or an alternative to convert your `.8xp` file to a `.txt` file.
+5. Create an `about.md` file in your program's folder with the following format:
+
+   ```markdown
+   # Program Name
+
+   Description of the program.
+
+   ## Credits
+
+   Author: Your GitHub username
+   ```
+
+   _You can include additional information in the `about.md` file, however you must always include a Description immediately after the program name header, along with the `Author:` in the credits section_
+
+6. Create a pull request to this repository with your changes.

+# Arithmetic Mean
+
+Calculates the arithmetic mean of a sequence of numbers. Given the first term of the sequence (AV1), the common difference (D), and the number of terms in the sequence (N), the program calculates the arithmetic mean of the sequence.

+# Compounded Interest
+
+Compounded Interest is a program that calculates the compounded interest of a principle amount over a given time period. The user can choose to solve for the principle, rate, time, or the answer. The program will then prompt the user for the necessary values and output the result.

+# Exponential Function
+
+Calculates the exponential function of the form Y=AB^X. Given two points (X1,Y1) and (X2,Y2), the program calculates the values of A and B in the exponential function. The program then displays the values of A and B, and the exponential function itself.

+# Exponential Growth and Decay
+
+Calculates a value from the exponential growth or decay formula Y=Ae^(KT). The user can choose between growth and decay, and then choose which variable to solve for. The program then prompts the user for the necessary values and calculates the desired variable. The program can solve for the final value (Y), initial value (A), factor (K), or time (T) in the exponential growth or decay formula. The program also accounts for decay by using the negative reciprocal of the factor (K) when solving for decay.

+# Exponential Growth and Decay
+
+Helps you find the exponential growth rate (T) or constant (K) based on the percentage of the original value. The user can choose to find either T or K by selecting the corresponding option, inputting the percentage, and the known value. The program then calculates and displays the result.
