This chapter enables us understand how information can be represented conveniently in a matrix form and how this information can be used in solving problems involving matrices, also, how the inverse of a matrix can be gotten and to know how a singular matrix is formed.
Matrices is one of the most important topics in the GCE ordinary level because it frequents every year and questions on matrices appears in both paper 1 and 2, hence taking this course will give you an advantage in having a good grade in mathematics.
At the end of this chapter, students are expected to know;
– The order of a matrix
– The types of matrices
– Equality of matrices
– Addition and subtraction of matrices
– Multiplication of matrices
– Transpose of a matrix
– Determinant of a matrix
– Singular matrices
– Adjoint of a matrix
– The inverse of matrix
– Solve simultaneous equations using matrix method
