INTRODUCTIONMATHEMA has found its way along the great path
of the implementation in the field of education forDisable student.
This software tool is based on syllabus from std. 1 &std. 7 Tamil Nadu state board text book.
MATHEMA Bringing out a wider scope in theprocess of learning Mathematics has enabled a cordialequality for all the students irrespective of theirdisability.

Studying mathematics is now not a great hindrance forthe students who are being remarked as disability.
MATHEMA clears up with the introduction of afabulous concepts namely:-

PROBLEM STATEMENT With the convenience of the use of the software, there has
been a distinction in the group of students who are beingenrolled under different type of disability.
The objective of this project is to enable the speciallyenabled to learn each and every exercise of std.3 and std. 4text book . This project has been developed in such a waythat everything can be done using clicks. Understandingcapabilities of mathematics can be largely improved whenthere is an interactive learning mechanism where the systemresponds to the user inputs and provides assistance for themusing diagrammatic representations. On considering thesefacts, this project provides both interactive learning ,diagrammatic representations and know yourself knowledgethrough test .

EXISTING SYSTEM There has been an application named Math Assistant-
v2 which has been supporting the limited features thathas not enabled many topic of mathematics such asfractional number , Daily Life Mathematics ,Number
description . It provides assistance in simple arithmetic calculations
like addition, subtraction, multiplication and division
It was bringing out the usability and has not pointedout with its portability to the students .it was usingpython language which is not platform independent.

MODULEConcept Gaining Lessons
This Module introduces a concepts of various mathematics topicslike DATA HANDLING, Mathematical operation on FRACTIONALNUMBER ,NUMBER DESCRIPTION(place value , Face value,L.C.M, H.C.F, number(even, odd, prime ,co-prime) ) , Daily LifeMathematics ( Percentage , Profit & loss, Simple Interest , Ratio) etc..
Concept Practice This Module introduces a worksheet with virtual keyboard, in that
they can practice the each topic.
KNOW YOURSELF
This Module introduces a worksheet with virtual keyboard bywhich user Evaluate the learning concept. This Module also use text to speech by which user listen text
problem then solve it by single mouse click.
