This topic focuses on finding the minor matrix from given 3x3 matrices. A minor matrix is determined by removing the row and column of a specified element in the original matrix. Each question presents a 3x3 matrix and instructs to find the minor matrix related to a specific element. Students are given multiple choices for each question, from which they must select the correct minor matrix. This practice aims to enhance students' understanding of matrix operations and their ability to manipulate and interpret matrices effectively.
