Finding the determinants of a matrix and using Cramer’s Rule or Gauss Jordan Elimination method can sometimes be easy to work with and sometimes, it can also be really frustrating.
Knowing that your work is done correctly in linear algebra operations can help you in building the skills you need in mastering operations in linear algebra. This video is showing you how I use free web application online to verify if my solutions and determinants for my matrices are correct:
