About this app

The Calculator provides the following features:
ALGEBRA
1. Computer science
2. Solving the equation:
3. Solve system equations
4. Graphing
5. Cartesian geometry sand(Viet Nam Education)
6. Unit Conversions
8. Simplify expressions
9. Polynomial factorization.
10. Binomial expansion Newton
11. Matrix: evalute matrix step by step

ANALYTICS
1. Derivative
2. Antiderivative
3. Definite integrals
4. Find the limit of the sequence, function

TRIGONOMETRIC
1, Trigonometric expand: sin(2x) -> 2sin(x)cos(x)
2. Trigonometric reduce: 2sin(x)cos(x) -> sin(2x)
3. Trigonometric to exponent: sinh(x) -> (e^x-e^(-x))/2

DETERMINATION OF STATISTICS
1. Combination
2. Permutation

SOME OTHER FEATURES
1. Prime factors
2. Modulo
3. Catalan number
4. Fibonacci number

The Calculator does not show the steps to solve the equations, system of equations, derivative... but only for the final result.
Enter sin(30°) to calculate sine Degree mode

The computer can work in two modes:
- Decimal mode: 0.12312312323
- Mode fractions: for results with arbitrary precision, for example 9^99999

Ratings and reviews

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. 😜

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.

New Edit: I'm finding many promised features non functional and Iam most disappointed with programming interface that is not delivering to even match the help provided... Old comment that I rushed to put strongly believing the promise....: Very good calculator and ...programabe! For some reason l can't find the decimal point when I want to enter a non integer number like...5.32... I am running it in an old android Samsung tablet and probably is a very isolated case. Again, l love this app!
