Learn how to perform the matrix elementary row operations. These operations will allow us to solve complicated linear systems with (relatively) little hassle!

Determine the matrix that is the result of performing a specific row operation on a given matrix.

This topic covers: - Adding & subtracting matrices - Multiplying matrices by scalars - Multiplying matrices - Representing & solving linear systems with matrices - Matrix inverses - Matrix determinants - …

Hopefully this at least gives you a decent understanding of what an augmented matrix is, what reduced row echelon form is, and what are the valid operations I can perform on a matrix without messing up …

What happens to the determinant when we perform a row operation. Created by Sal Khan.

Matrix is an arrangement of numbers into rows and columns. Make your first introduction with matrices and learn about their dimensions and elements.

Each row operation corresponds to a valid operation on the system of equations, like adding two equations together, writing them in a different order, or multiplying by a constant.

Aprende a realizar las operaciones elementales en renglones de matrices. Estas operaciones también nos permitirán resolver sistemas lineales complicados, ¡con (relativamente) poco esfuerzo!

The dimensions of a matrix give the number of rows and columns of the matrix in that order. Since matrix A has 2 rows and 3 columns, it is called a 2 × 3 matrix. If this is new to you, we recommend …
