# Mathematics A

Course

The study of financial, geometric, statistical, and operational mathematics.

Mathematics A will assist to:

- Develop knowledge and skills of computation, estimation and measurement;
- Help manage financial affairs in an informed way;
- Develop the capacity to interpret and analyse information presented in a variety of forms;
- Make judgements based on evidence and reasoning.

Here is the course outline:
