Math 9th Class|Ch#1|EX#1.3 Math 9th Class|Ch#1|EX#1.3 In Chapter 1, Exercise 1.3 of 9th-grade mathematics, you're likely dealing with addition and subtraction of matrices. Here's an outline of how to approach these problems: 1. Matrix Addition To add two matrices, they must have the same dimensions (i.e., the same number of rows and columns). 2. Matrix Subtraction Matrix subtraction follows the same rule as matrix addition. The matrices must have the same dimensions, and the result is calculated by subtracting the corresponding elements: Steps for solving matrix addition and subtraction: 1(Check if the matrices are of the same order (same number of rows and columns). 2(Add or subtract the corresponding elements of the matrices. 3(Write the resulting matrix.
