Matrix Multiplication and Operations

This video tutorial explains how to multiply 2x2 matrices, starting with an introduction to the concept and a detailed walkthrough of two examples. The first example involves basic multiplication, while the second introduces negative numbers. The video emphasizes the consistent pattern of multiplying rows by columns and adding the results to form a new matrix.
