Introduction
     Handwriting recognition is the ability of a computer to receive and interpret intelligible handwritten input from sources such as paper documents, photographs, touch-screens and other devices. The image of the written text may be sensed "off line" from a piece of paper by optical scanning (optical character recognition) or intelligent word recognition. Alternatively, the movements of the pen tip may be sensed "on line", for example by a pen-based computer screen surface or mobile device.

Motivation 
     As the Arabic language is considered one of the most used language in the Middle East, It’s not commonly used in the modern technology and most of the handwriting applications don’t consider the Arabic language in its implementation, So we decided to enhance the Arabic handwriting recognition by developing an android application that allows user to write a mathematical equation using handwriting technique then the application recognizes the mathematical equation and solve it immediately.

Main Work
     We can divide our application’s main work into main seven parts:
a-      Data collection
Making an android application that collects sample data of handwritten numbers and operations then saving the collected data as pixels.

b-
      Data preprocessing
Converting all collected data images to suitable fromat for training phase.

c-      Symbol recognition training
Using Google TensorFlow to train on the data using the images and labels to develop a recognition model.

d-      Expression reading and segmentation
Dividing the input expression into symbols to recognize each symbol.

 e-      Symbol recognition
Using the trained model to recognize every symbol in the equation.

f-      Number construction
Grouping the related digits to construct the numbers.

g-      Expression construction
Grouping the numbers and operations to construct the equation in postfix form.

h-      Expression evaluation
Solving the constructing equation and viewing the result.

Supported digits and operations
- Digits (
٠, ١, ٢, ٣, ٤, ٥, ٦, ٧, ٨, ٩)
- Operations (+, -, ÷, ×, =,
جا , جتا , ظا , /, (, ), √)
