This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
This unit will enable students to represent numerical data in a rectangular array and perform the simple operations on a matrix. The unit will also enable students to define and classify graphs.

A person credited with this unit standard is able to:
  • Arrange numbers in a matrix and perform matrix operations to facilitate problem solving.
  • Solve systems of linear equations by diagonalisation or determining the inverse matrix.
  • Define different types of graphs and associated properties.
  • Identify and use walks, paths and circuits in graphs.

    In order to see this unit standard with its exact formulae, please use the link at the end of the Searchable Database home page. SAQA is in the process of adapting the National Learners' Records Database to accommodate such formulae. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    A working knowledge of the solution of simultaneous equations in two variables and representation of two dimensional geometrical figures, NQF Level 2.

    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
