- Matrices: are a man made contrivance. -Master Yoda
- Matrices are always identified as capital letters. ex: A= [ ]
- AxB DOES NOT ALWAYS EQUAL BxA
- BUT... A+B = B+A
- Gauss Elimination: the process to put a matrix in row echelon form.
- Gauss-Jordan Elimination: the process of puttin matrix in REDUCED row echelon form.
- Row Echelon Form (see picture)
- Reduced Row Echelon Form (see picture)
