The prevalence of mobile devices has equipped technology with greater penetrating power to benefit people’s life in terms of convenience and people have highly depended on various search engines to search for answers, solutions and information. Mathematics is a subject that can incorporate technology into the learning and teaching materials due to its special nature in terms of the formula, special symbols, pictures that are presented in the question body, instead of just plain texts. This problem is not trivial since the mathematical documents are highly symbolic and structured, increasing the complexities of information retrieval and content display. Hence, there is an increasing need for a mathematical question search engine specially catered to search of math questions. This project aims to enhance students’ learning experience by providing a user-friendly platform to search for mathematical documents. By assessing the existing Mathematical mobile applications MathQA and Math Search, this project develops a new application, MOE Math, which has higher usability, with the implementation of a versatile search engine, math paper generation, question uploading functionality, and with the incorporation of Optical Character Recognition (OCR) and image preprocessing features. This project is divided into three phases: 1) Enhancement of the existing web system 2) Reviewing of two existing mobile applications, MathQA and Math Search 3) Development of a usable and robust application, MOE Math. With exercising good design principles and following Agile software lifecycle, this project ensures a flexible, extensible, and efficient mobile application to facilitate mathematical learning experience.
