3 <p>A matrix is an arrangement of data in rows and columns. Subtraction of matrices means the subtraction of the corresponding elements, which involves two or more matrices. The subtraction of matrices is a similar process to the addition of matrices; we add in the addition, but we need to subtract the matrix in the subtraction of matrices.</p>

11 <p>Matrix subtraction is the process of subtracting two<a>matrices</a>that have the same dimension. A matrix with ‘m’ rows and ‘n’ columns, then the dimension of the matrix is m × n. To subtract two matrices A and B of the same size, you subtract their corresponding elements. It is represented as\( (A - B)ij = Aij - Bij\), where Aij and Bij are the elements in the matrix in the i-th row and j-th column. Let’s learn the subtraction of matrices of order n × n, 2 × 2 and order 3 × 3.</p>

14 <h3>Subtraction of n × n Matrices</h3>
13 <h3>Subtraction of n × n Matrices</h3>
15 <p>The subtraction of n × n matrices refers to subtracting two corresponding elements of two squares of the same size. Here, n represents the number of rows and columns in the matrix operation, which indicates the matrix is of order n ×n. For example, there are two matrices, A and B, both of order n × n. Then, their subtraction A-B is done by subtracting each element of matrix B from the corresponding element in matrix A.</p>

21 <h3>Subtraction of 3 × 3 Matrices</h3>
23 <p>The Subtraction of 3 × 3 matrices involves subtracting the corresponding elements of two matrices, each having three rows and three columns. This operation only works when two matrices are of the same order (3 × 3). For example, if A and B are the order of matrices in 3 × 3, the difference A-B is calculated by subtracting each element of matrix B from the corresponding element of matrix A.</p>
