Abstract: Functions of elementary row operation of matrix, row reduced echelon matrix, augmented matrix, and visual solution of system of linear equations, are programmed in Mathematica 7.0 environment. Then two types of usages of the function of visual solution of system of linear equations are also discussed: users who are familiar with Mathematica 7.0 can input function with parameters to solve the system of linear equations; while any users can conveniently input the number of equations and variables, and augmented matrix after inputting function without parameters, and finally the process and general solution of the system of linear equations are output just by clicking solution button.

Key words: Methematica software, elementary row operation of matrix, system of linear equations, augmented matrix, visualization
