The document describes a calculator application for Android that features basic mathematical operations, extended functions, complex number calculations, graphing capabilities, and matrix operations. It has two main advantages: showing intermediate calculation steps and building accurate graphs based on computations. Compared to traditional calculators, the Android app has advantages in size, power requirements, accuracy, cost, and usability due to its installation on smartphones. The application uses three key files - Main.XML for layout, CalculatorActivity.java for functionality, and AndroidManifest.xml for configuration.

3. Features:
• Addition, subtraction, multiplication, division.
• Extended functions, such as logarithms, SIN,
COS, irrational numbers like pi and e.
• Calculation of complex numbers.
• Construction of function graphs.

4. • Working with matrices: addition,
multiplication, determinants, and eigenvalues.
• Supports work with hexadecimal and binary
numbers.
• The application gives fast and accurate result.
• Support for tablets and smartphones.

5. Advantages:
• The application has two main advantages:
• It shows the results of intermediate
calculations, as long as they are typed in the
input line.
• Based on the computations, the calculator
builds accurate graphs and generates values
along the coordinate axes.

6. Comparison/Scope:
• The comparison between existing traditional calculators
and the proposed Calculator app for Android can be
done in the following points:
• Size: The separate calculators are larger in size due to
use of own circuit board whereas android calculator is
installed in cell phones.
• Power: A small battery power of cell phone is enough
for running android calculator but traditional calculator
consume comparatively higher power.
• Accuracy: The accuracy of both the calculators depends
upon their programming. Calculators can be designed
for the desired accuracy.

7. • Cost: Android Calculator, being an application,
can be downloaded free of cost and installed
on phone. The traditional calculators have
their own hardware. As a result of this, they
need to be purchased.
• Ease and comfort: Most of the android cell
phones are of touch screen type. So,
calculator app Android is easy and
comfortable to use.

8. Files:
There are three files which are used in this
application.
• Main.XML
• Calculator activity
• AndriodMainfest.xml

9. How application will be Run?
• When the Calculator App is
executed, Main.Xml layout code will run. This is
the first design layout that will load features such
as height, width, background details, etc. Then,
the java file, calculator activity, will load design
parameters like buttons, click functions, text
display, etc. AndroidMainfest.xml is the main
configuration file of the project that will load the
main layout by default.
