FX-991MS Scientific Calculator
Functions:1) Basic Math Operations such as divide,add,subtract,multiply,modulo,factorial etc2) Can calculate nth root of a number3) Can calculate factorial up to 50004) Can Evaluate log with decimal base5) Trigonometric Functions 6) Number Base Conversion from 2 to 167) Matrix operations such as to find Inverse, Adjoint, cofactor,rank and determinant. Perform addition, multiplication and subtraction of Matrices 8) You can perform operations on large numbers9) Can Calculate exponent with decimal power10) 40+ constantsNote :ln(23)^2 will be evaluated as ln(23^2) i.e. first 23^2 will evaluated which is 529 then ln(529) will be evaluated. If you want ln(23) should get evaluated first then write (ln(23))^2. Please use parentheses to get proper result otherwise you will get unexpected result.
This scientific calculator is made to make editing of large expressions easy. I have faced situation in my engineering where I have to write large expressions with little changes again and again. So I made this scientific calculator where you can easily edit and write large expressions. One more great feature of this scientific calculator is that you can deal with large numbers i.e. you can even calculate Factorial of 5000. One more thing you don't need to press shift this will save lot of time.
Please share and rate it 5 if you like it. I will regularly add more functions to it.

Very bad app, answer button doesn't work.
Thank you for providing this app
The app is so bad
After a long search I finally got the kind of calculator that I wanted. I think it may the best calculator app right now especially with most others trying to sell paid versions while their apps are getting even dumber than before. They think stupid intuitive actions like putting brackets (in the wrong places), and a fancy look will make their app worth selling. I got so fed up trying out those worthless calculators. Thank god that I stumbled upon this app. It is the most logical calculator just like the Casio calculator with same model number which I am very used to. Good job developers! I would like to buy add free version.
Expressions like (4 by 11) whole divided by (3 by 7) takes time to express on it
Very good apps and very user friendly. I think,continuous development will make it one of the best calculator.Best wishes for the working team.
please make the input screen big and allow us to hide the scientific bottoms . I love the editing option. plz do it
Very useful app, very functional, just wish there were more options for constants, for example constants for astrophysics.
Best calculator I have ever used in my android phone with tons of feature that no other calculater provide at no cost,Hats off to you guys for giving us such an awesome app absolutely free.
Now what is the most important of the fx-991Ms compared to the other calculators is the M, which indicates is has the engineering symbols available. I don't see any of that option at all anywhere. Also the buttons are way too big. they could be half the size, and than all would fit in the display.
It is the copied version of original calculator.Working with almost all the functions as the hand calculator have.As an engineer ,I need this.This functions all with much ease.Thanks for your team for such a wonderful and hard developments.
Not just 5 star but 10 star app. Perfectly perfect. Lol.
The main good quality is to see the history clearly with the mathematical operations in "History" information
It has many more features i didnt expect.
Finally got a scientific calculator. Best calculator I have ever used. Thanks for the app.
The best calculator for both science and engineering students. Super fast
It is very helpful for me and i don't have to buy a calculator thanks to this app
Such a good calc i have seen on playstore
This is a fantastic calculator with a clean interface. Thumbs up!
It is very useful to solve matrix problems excellent....
Great app , response from developor team is awesome .
Thanks for developers of this app. It's much useful.
Awesome app I thank to create whole team
Its nice, very easy to use
It looks useful. Just started using.
Thanks for the my life and I was a great calculater
