||Flexi-EQ Solver which also called as Flexible-Equations Solver is a flexible interface featuring step-by-step exploration solutions to exponential, logarithmic, square and square root, decimal, percentage and fraction equations. It engages users in algebraic ways of thinking to solve any form of linear systems of equations. The ability to solve linear equations is the foundation for mastering many concepts in Algebra, but there is evidence that user’s understanding of the concept is often minimal. It has been advocated that user should explore many aspects of each concept through multiple representations, especially when solving problems. Many researches stress the importance of developing user's ability to solve problems that can be modelled by means of linear equations a variety of representational modes. Through Flexi-EQ Solver, user is able to manipulate different forms of equations to understand multiple expressions of equations, solve multiple equations, reset the equations, try again and see where they tend to make mistake. It gives chance to users to gain hands-on approach as the users can manipulate and make flexible experience on equations by themselves. Flexi-EQ Solver uses visual learning theory to visualize number equation idea, understand number equation by seeing, touching, hands on and manipulating it. Research has shown that visual learning theory is especially appropriate to the attainment of mathematics skills. Flexi-EQ Solver offers flexible continued practice and elevating experience to the user when trying to recognize number sense as well as dealing with mathematics equations and symbols. Its novelty lies in the active participation from all users to be able to improve their calculation skill while boosting confidence in mathematics.
