The EquationSolver is carefully designed to be a simple and elegant app. Easy to use, easy to understand, simple and effective It solves system of linear equations, simultaneous linear equations (no limit on the number of equations). It also teaches you the steps to solve such systems. To find a solution, it uses Matrix inversion method or LU decomposition method when inverse is not possible or complicated. The equations are beautifully presented in both: 1) Set of individual equations form 2) Matrix-vector product form. You can also share the beautifully written solution It automatically saves your hard work locally on your device so you can come back and pick up from where you left off as your great effort will not be lost. This is a perfect app if you are a student learning to solve these kind of equations. There is also a Study page to help you with learning some important linear algebra formulas. This is an app for all student groups. From high school to college to university students. Be creative. Enjoy the app!

About

Linear Algebra World

This app offers a rigorous yet accessible approach to linear algebra, combining a matrix calculator, interactive algorithm visualizer, and a structured learning path. It aims to build intuition through visual tools and a coherent system based on axioms, suitable for students and instructors.

Linear Algebra World (LAW) presents linear algebra in a way that is accessible yet rigorous. It is designed for students of engineering, mathematics, data science and related fields, and may also serve as a visual presentation tool for instructors. The app combines three roles: • matrix calculator • interactive algorithm step visualizer • carefully designed learning pathway through linear algebra Our goal is to present linear algebra as a coherent system built on a small set of axioms. Definitions are separated from consequences, logical dependencies are made explicit, and notation is kept minimal to reduce cognitive load. Visual tools are used extensively—even for abstract topics such as the four fundamental subspaces—so that geometric intuition and algebraic reasoning reinforce one another. The curriculum begins with vectors as coordinates and matrices as collections of vectors, and currently covers topics through QR factorization. Upcoming additions include OLS, eigendecomposition, SVD, and PCA. This app builds on our earlier Matrix Solver Step by Step, a highly rated matrix computation app used by students for several years. LAW adds a structured curriculum along with LaTeX import and export. LAW is designed for serious learners who want to understand the structure behind the computations. For quick step-by-step matrix calculations, Matrix Solver Step by Step may be the more direct tool. Your constructive feedback is essential to the continued refinement of the app.
