Timothy Law

Very good, with only one minor issue So far so good, exactly what I wanted, all bundled into one. The only down side is the 3D graph lacks axis labeling. I don't know how the 3D graphs are oriented.

Arther Casillas

Nice calculator Wish I could make the button bigger or adjust the DPI. It would be nice if the calculator history could be viewed by swiping right as to make the number pad larger to.

Allen Holmes

Really useful Could use left and right tab keys for easier editing. Otherwise a superior, comprehensive calculator.

User reviews

Graphing I would have given this a five star rating. I do have some complaints. First, that on 2D graphs, you can't change the scale on just one axis. I think it would be very useful for an option to scale one axis at a time when looking at a graph that may be very tall or very wide. There is no option for polar functions (r=Ø, etc. (i don't have a symbol for theta)). I would like to be able to graph two 3D functions at once. Other calculators support that. Question: How do you graph a ripple effect like that?

Permissions change Update: Though slow to respond the explanation to the new permissions change is acceptable. Otherwise a rather feature filled app. Previous: So why does the update need to read phone logs and identity?

BisMag dev May 15, 2013

Scientific Calculator Plus is a powerful mathematical tool to do mathematical analysis and evaluate complicated mathematical expressions similar to Matlab. More than Matlab, it has capability to take photo of printed math expressions and recognize them to do further analysis. It supports complex number, matrix, (higher level) integration, 2D, polar and 3D chart, string, programming (using a easy-to-use language called MFP), file operation and unit conversion. It can run in both Android phones and tablets, PC or MAC with JAVA ready (Scientific Calculator for JAVA does not support math recognition).

Main capabilities:

1. Math recognition: User enter into Smart Calculator and then click the camera button to take photo of one or more than one printed math expressions to recognize. User is able to choose to calculate or plot graph or simply use the recognized text as input. Comparing to Photomath, Scientific Calculator Plus is a bit slower at recognition speed. However, it supports a lot more expressions types than Photomath. And it is able to plot chart of expressions.

Scientific Calculator Plus supports the following expressions: 1. Addition; 2. Subtraction; 3. Multiplication; 4. Division; 5. Fractions; 6. Roots; 7. Multiple linear expressions; 8. Trigonometry; 9. Polynomials; 10. Exponents; 11. Algebra; 12. Integration; 13. Summation; 14. Product; 15. Matrix and 16. Complex value. User can also send email to us if the recognized result is not satisfactory.

2. Back-end math engine: Scientific Calculator Plus supports complex number, matrix, integration and is able to solve multi-variable linear equations, polynomials (up to 6 order) and other simple functions.

Example to input matrix: [[1,2],[3,4]], where [1,2] and [3,4] are 2 rows in the 2*2 matrix.

Example to input complex number: 8.71 - 5.44i where i is the image unit, the times operator, which is *, between 5.44 and i can be ignored. If ignored, no space is allowed between 5.44 and i;

Example to input integral: integrate("x**2", "x", 0, 1) (definite integral of x square from x = 0 to 1) or integrate("x**2","x") (indefinte integral of x square).

3. Graph engine: This app is able to plot 2D, plor or 3D chart. In smart calculator, user inputs the expressions and Scientific Calculator Plus automatically identifies the number of variables (2 variables means 2D chart or polar chart, depending on variable name; 3 variables results in 3D chart) in the expressions and draws corresponding graph. Scientfic Calculator Plus also provides stand alone tools to draw complicated graphs and a set of functions to draw charts from command line.

4. Programming: This app is actually a shell of programming language called MFP. This language internally supports string, complex number and matrix and is able to call all the built-in functions and all the user-defined libs stored in AnMath/scripts folder in SD card. This programming language also provides a complete set of file operation functions and time / date functions. Theoretically, user can do anything using this programming tool in an Android device.

Main components:

1. Smart calculator: User can take photo to recognize math (printed only), do any calculation or plot graphs using this tool. An internal calculator assistant can convert units and return constant values. Its input pad is configurable. User can add his/her own function buttons.

2. Command line: A matlab like tool for advanced users. User inputs functions line by line and run. Its key board is also configurable.

3. Integration and plotting graphs: Tools calculate complicated integrals and plot various graphs.

4. Scientific Calculator for JAVA: It is included in Scientific Calculator Plus for Android. User is able to connect the mobile device to any PC or MAC via a USB cable, copy SDcard\AnMath\ folder to his/her own directory and launch the JMathCmd.jar in it. Note that SCP for JAVA is not able to recognize math expressions.

## Auto Reply/Block

This application allows you to automatically answer or block a call after receiving an incoming telephone call.

This is very useful when it is not possible to be distracted, to answer or block call.

Features description:

- Selective call answer or block:

-- answer or black all calls

-- answer or block calls from a list

-- answer or block calls from hidden number

- Notification for display application and quick access to the settings

A further feature of this application is the ability to add exceptions, function very useful when we need, for example, to answer or not answer all incoming calls except a few.

For example, if you select to block all incoming calls by adding the exceptions of a few numbers, the phone will block all incoming calls except those received from the numbers in the exception list.

The application provides the ability to add numbers to the lists in several ways:

- Directly from the contact list of our rubric

- Or manually: here being able to choose whether to enter the entire phone number or the first digits or middle digits or the last digits.

## Sliding Puzzle

The 15-puzzle (also called Gem Puzzle, Boss Puzzle, Game of Fifteen, Mystic Square and many others) is a sliding puzzle that consists of a frame of numbered square tiles in random order with one tile missing. The object of the puzzle is to place the tiles in order ,by making sliding moves that use the empty space.

The puzzle also exists in other sizes, particularly the smaller 8-puzzle. If the size is 3×3 tiles, the puzzle is called the 8-puzzle or 9-puzzle, and if 4×4 tiles, the puzzle is called the 15-puzzle or 16-puzzle named, respectively, for the number of tiles and the number of spaces.
