This is a simple Lua application for the PSP that has 7 useful mathematical functions built into it.

## User guide

These are the 7 functions built into the program:

- Convert equations from standard form to y-intercept form.
- Convert equations from y-intercept form to standard form.
- Find the determinant of a 2x2 matrix.
- Find the determinant of a 3x3 matrix.
- Find the solution to a system of 2 equations with 2 variables*.
- Find the inverse of a 2x2 matrix.
- Simplify a fraction.

(*) This means that it finds the intersection of two lines in standard form

Controls are displayed on the screen.

## Changelog

**Version 0.2**

- Got rid of the find slope and y-intercept option and replaced it with the equation conversions (standard to y-intercept and vice versa). The standard to y-intercept still says the slope and y-intercept, though.
- Added function to find the inverse of a 2x2 matrix.
- Added function to simplify any fraction into its simplest form.

**Version 0.1**

- Initial Release.
- Features:
- Find slope and y-intercept of a line in standard form.
- Find determinant of a 2x2 matrix.
- Find determinant of a 3x3 matrix.
- Find the solution to a system of 2 equations with 2 variables.
