Linear algebra is motivated by solving a system of linear equations. In this course, you will learn how to solve a system of linear equations with a general strategy---the echelon form. Through echelon form, we are able to read the essential information of the equations (basis and rank) and the solutions (null space and nullity). The equations and the solutions can be described by vector spaces. We will learn how to find the basic information of a vector space, including the basis, the rank, and the operations on them. We will study the maps between vector spaces and learn how to write down a matrix representation for them.
