In this chapter, we will be learning about matrices and basic operations on matrices. Matrices are rectangular arrays of numbers or symbols. We will learn how to represent information from real situations in the form of matrices. We will also learn how to determine the order of a matrix, which helps us identify certain elements in a matrix. This chapter will provide us with the foundation to solve problems using matrices and understand their applications in various fields.
• Represent information from real situations in the form of matrices.
• Determine the order of a matrix, hence identify certain elements in a matrix.
• Determine whether two matrices are equal
• Add and subtract matrices
• Multiply a matrix by a number.
• Multiply two matrices.
• Explain the characteristics of identity matrix
• Explain the meaning of inverse matrix and hence determine the inverse matrix for a 2 × 2 matrix.
• Use the matrix method to solve simultaneous linear equations.
• Solve problems involving matrices
