Subject descriptor:

General Mathematics is a full year (20 credit) subject that extends students’ mathematical skills in ways that apply to practical problem-solving. A problem-based approach is integral to the development of mathematical models and the associated key concepts in the topics.

These topics cover a diverse range of applications of mathematics, including personal financial management, the statistical investigation process, modelling using linear and non-linear functions, and discrete modelling using networks and matrices. Successful completion of this subject at Stage 2 prepares students for entry to tertiary courses requiring a non-specialised background in mathematics.

Stage 2 General Mathematics consists of the following six topics:

  • Topic 1: Modelling with Linear Relationships
  • Topic 2: Modelling with Matrices
  • Topic 3: Statistical Models
  • Topic 4: Financial Models
  • Topic 5: Discrete Models
  • Topic 6: Open Topic

Students study five topics from the list of six topics above. All students must study topics 1, 3, 4, and 5.
