Android app to check mathematical operations in real time through the camera

Main functionalities:

1. camera scanning:

- Continuous viewing from the phone's camera

- Clearly marked scanning area on the screen

- Ability to use both front and rear cameras

2 Text Recognition (OCR):

- Detection of stored mathematical operations

- Support for various writing formats (e.g. “2+2=4” or “2 + 2 = 4”)

- Handwriting recognition

3 Math Verification:

- Verifying the correctness of simple operations (+, -, *, /)

- Handling actions with parentheses

- Handling multi-step operations

- Multiplication

4 User interface:

- Clear camera view

- Frame indicating the scanning area

- Immediate indication of correct operation

- Display of correct result in case of error

Technical requirements:

1. Android system (min. version 6.0)

2. use of ML Kit for OCR

3. use of CameraX API

4. support for different screen resolutions
