The Universal Calculator

The Universal Calculator is a scientific graphing calculator that offers a myriad of calculation features which extends beyond most graphing calculators. While it can be used for its standard Calculator and Graphing capabilities, it also calculates:
- Polynomial Factorization
- Polynomial Multiplication and Division
- Integer Factoring
- Prime Integer Factoring
- A Plethora of Unit Conversions
- Matrix Addition, Subtraction, and Dot Product
- Matrix Inverse, Transpose, Adjugate, and Cofactor
- Matrix Upper Triangle, Lower Triangle, and Diagonalization
- Matrix Determinant and Eigenvalues
- Triangular Geometry Calculations
- SAE to Metric Measurement Conversions
- Tips for Bills


Enjoy a calculator history capable of storing 100 of your previous calculations. Each history line is selectable, allowing you to insert the equation or answer into your current equation! It also contains 15 common scientific constants for ease of use.

For the Graphing inclined, graph in color for up to 10 equations simultaneously and intuitively zoom in and out like you would a photo! You can also calculate their intersections, trace the equations for a finer look at the values, graph an equation equal to y-squared, customize the thickness and color of each equation, and much more!

Personalize your Universal Calculator experience in the settings options. The Universal Calculator contains 6 different color themes, 7 different sound options, haptic feedback, and more.

Lastly, enjoy peace of mind knowing that the Universal Calculator will never collect your information, and will never contain ads. This is an essential part of this ongoing project which is taken very seriously. If you have any suggestions or find any bugs, please reach out!
