# Linear Algebra Basis

### The book begins with systems of linear equations then covers matrix algebra before taking up finite dimensional vector spaces in full generality.

**Linear algebra basis**.
To say that it was drastically different and more difficult from my first lin al textbook would be an understatement.
A basis b of a vector space v over a field f such as the real numbers r or the complex numbers c is a linearly independent subset of v that spans vthis means that a subset b of v is a basis if it satisfies the two following conditions.
In this course on linear algebra we look at what linear algebra is and how it relates to vectors and matrices.
We will begin our journey through linear algebra by defining and conceptualizing what a vector is rather than starting with matrices and matrix operations like in a more basic algebra course and defining some basic operations like addition subtraction and scalar multiplication.
Equivalently a subset s v is a basis for v if any.
