About this app

The Calculator provides a comprehensive set of tools for algebra, calculus, trigonometry, statistics, and more. Designed for students, engineers, educators, and math enthusiasts, it offers a powerful CAS programming engine (Symja) and an intuitive interface for everyday calculations and advanced problem-solving.

ALGEBRA

1. Computer science functions
2. Solve equations
3. Solve systems of equations
4. Graph functions
5. Cartesian geometry
6. Unit conversions
7. Simplify algebraic expressions
8. Polynomial factorization
9. Binomial expansion (Newton's formula)
10. Matrix calculations

CALCULUS

1. Derivatives
2. Antiderivatives
3. Definite integrals
4. Limits of sequences and functions

TRIGONOMETRY

1. Trigonometric expansion: sin(2x) → 2sin(x)cos(x)
2. Trigonometric reduction: 2sin(x)cos(x) → sin(2x)
3. Convert trigonometric and hyperbolic functions to exponential form

STATISTICS & COMBINATORICS

1. Combinations
2. Permutations

ADDITIONAL FEATURES

1. Prime factorization
2. Modulo calculations
3. Catalan numbers
4. Fibonacci numbers

The calculator supports two computation modes:

- Decimal mode: e.g., 0.12312312323
- Fraction mode: precise symbolic results, e.g., 9^99999

This combination of CAS programming and extensive math functions makes the app a reliable tool for learning, teaching, and technical work.

One of the few free Android scientific Calculators that are really without ads nor in-app purchases. Quite a large spectrum of usage. If you want the complete app, it seems you need to compile it. This one is the light version, if the Readme.md on GitHub is correct. It lacks graphing tabs, but the plot functions are available through the Programming tab. Great job. Keep up the good work!

Abandoned. The calculator always starts with the same input I typed just after I downloaded the app, and I have to clear it each time. The console is really annoying to use. Why can't I add more computation cells? Why can't I hide the obstructive syntax error messages? The code window sometimes decides to scroll to the top after scrolling down for no reason. Sometimes the output window is just blank when plotting.

I have not used all of the programmable functionality, but I'm happy to see it's available. [Edit] It took me _way_ too long to figure out the blue and red additional functions, etc. can be reached by simply pressing the button longer. This is not a criticism, but a confession. I was unable to find any documentation about how to use the phone screen interface, but it never dawned on me that it worked like every other phone app. 😜
