Using Excel in Mathematics: A Proposal for Solving System of Linear Equation Problems with 3 unknowns

Abstract

This article proposes an innovative approach to solving systems of linear equations with 3 unknowns, using Microsoft Excel as a central tool. We have developed a spreadsheet that not only calculates the system's solutions but also instantly classifies its properties. The proposal aims to streamline and enhance the resolution process, offering an effective alternative for dealing with complex mathematical problems. We explore the structure of the spreadsheet, highlighting its applicability in educational and professional contexts. Beyond optimizing resolution time, the presented approach seeks to strengthen students' conceptual understanding of linear systems. This work represents an advancement in using technology to improve efficiency in solving mathematical problems, showcasing the potential of Microsoft Excel as a valuable tool in mathematical education.
