Development of matrix calculator learning media

Abstract

The purpose of this research is to design dan develop an android-based matrix calculator learning media. This type of research is research and development. The model used in research development is the ADDIE model which consists of five stages namely Analyze, Design, Development, Implementation, and Evaluation. The matrix calculator learning media developed has met the feasibility of valid, practical and effective media. The difference with other matrix calculator application is that in this application there is a solution to a three-variable system of linear equations using the Cramer method. Where is the Cramer method in its completion using matrix arithmetic operations.
