This week you have learned about matrices. Matrices are useful for solving a variety of problems, including solving systems of linear equations which we covered last week. Consider the approaches you learned last week compared to the topic of matrices from this week. How are the methods for solving systems of equations from last week similar to using matrices? How do they differ? Can you think of a situation in which you might want to use the approaches from last week instead of matrices? How about a situation in which you would prefer to use matrices?
