The video tutorial by Rick explains how to perform matrix calculations using the TI-36X Pro scientific calculator. It covers accessing the matrix menu, entering matrices, performing basic operations like addition and multiplication, and using advanced functions such as determinant and transpose. The tutorial also demonstrates working with identity and inverse matrices and concludes with instructions on resetting the calculator to clear stored data.
