Calculator++ Fx is a powerful tool that meets the needs of students, teachers, engineers and everyone who studies mathematics or does simple or advanced calculations.
The main task of Calculator++ Fx is to provide access to a huge variety of functions and advanced features being able to edit the expressions in their mathematical form so that they look as on a blackboard or textbooks, at the same time keeping to be simple, practical, but fancy and elegant.
Its simple and handy interface allows to form and view the solutions of the expressions easy and conveniently.
Calculator++ Fx can quickly draw the graph of a function, solve system of linear equations, do vector calculations, matrix calculations, operations with complex numbers; but it, as well, can store data and later recall it from the memory.
The application has the ability both to save graphics, systems of equations, history calculations as images in photo library/album; and to email them as images or PDF files. Calculator++ Fx provides 1200++ constants, all of them being grouped by categories.


FEATURES:
- writes expressions in their mathematical form so that they look as on a blackboard or a textbook
- simple and elegant interface for easy use
- backspace, delete, and navigation keys commands to move and delete any part of the equation
- basic and advanced calculations (trigonometric, series, numeric integrations, finding roots, converting values between rectangular, polar form’s, etc)
- complex numbers calculations
- vector calculations
- matrix calculations
- solving systems of linear equations (systems can be exported as images or pdf files)
- storing and graphing up to 8 expressions (graphs can be exported as images or pdf files)
- saving all calculations in history (history can be exported)
- 1200+ constants
- storing and recalling data in/from memory slots or ANS(answer)
- 15 memory slots for storing data (can store real or complex numbers, vectors and matrices)
- independent memory (M) (can store real numbers by adding(M+) or subtracting(M-) )
- support for octal, hexadecimal and binary calculations
- long lasting calculations don’t freeze the app, in such a way calculations can be canceled just by pressing any button.

This app is constantly improving and will have upgrades for really more complex calculations and featured aspects.
