Why we learn Additional Mathematics for Engineering

The Importance of Additional Mathematics in Engineering

Additional Mathematics is a subject that significantly enhances problem-solving and analytical skills. It’s particularly important for students aspiring to be engineers, as it equips them with the skills to comprehend and apply mathematical concepts effectively.

What is Additional Mathematics?

Additional Mathematics is a subject offered in the General Certificate of Education (GCE) Ordinary Level examinations. The course is more advanced than Elementary Mathematics and is intended to prepare students for further studies in Mathematics, Sciences, or Engineering. It is designed to develop mathematical knowledge and skills in algebra, geometry, calculus, and trigonometry, among others.

The syllabus is divided into three main assessment objectives:

  • AO1: Use and Apply Standard Techniques — This objective tests the student’s ability to recall and use facts, read and use information directly from various sources, and execute routine mathematical procedures.
  • AO2: Solve Problems in a Variety of Contexts — Here, students need to interpret information to identify relevant mathematical concepts, make connections across topics, and apply appropriate mathematical techniques to solve problems.
  • AO3: Reason and Communicate Mathematically — This section assesses the ability to justify mathematical statements and explain them in the context of a given problem.

Why is Additional Mathematics Important for Engineering?

Foundation for Engineering Principles

Additional Mathematics covers a wide range of topics, many of which form the foundation of engineering principles. Concepts such as quadratic functions, surds, polynomials, exponential and logarithmic functions are all applied in various fields of engineering.

For example, electrical engineers regularly use complex numbers and exponential functions to analyse circuits. Mechanical engineers use calculus and differential equations to model and predict the behavior of mechanical systems.

Development of Problem-Solving Skills

The syllabus for Additional Mathematics requires students to solve problems in a variety of contexts, encouraging the development of strong problem-solving skills. This is an essential skill in engineering, where complex real-world problems often require innovative solutions.

Enhances Analytical Thinking

Additional Mathematics also emphasizes reasoning and mathematical communication. This encourages students to think analytically and to clearly and succinctly explain their thought processes. Analytical thinking is key in engineering, as it allows engineers to understand complex systems and develop effective solutions.

Preparation for Further Study

Additional Mathematics provides an excellent foundation for further study in engineering. Many of the topics covered in this course will be explored in greater depth in undergraduate engineering courses. Therefore, students who have studied Additional Mathematics will be better prepared and will find these higher-level courses more manageable.

Additional Mathematics in Various Engineering Fields

Different fields of engineering emphasize different aspects of Additional Mathematics:

  • Mechanical Engineering: Utilizes calculus to describe and predict system behaviors and to design control systems.
  • Civil Engineering: Geometry is used to design structures and ensure they can withstand various forces, while trigonometry is used in surveying and creating accurate scale models.
  • Electrical Engineering: Complex numbers and exponential functions are used to analyze electrical circuits, while calculus is used to understand signal processing.
  • Chemical Engineering: Differential equations are used to describe chemical reactions and the flow of heat and materials.


In conclusion, Additional Mathematics is a crucial subject for any aspiring engineer. It lays the foundation for many of the mathematical concepts used in engineering and develops the problem-solving and analytical skills needed to be successful in the field. By gaining a solid understanding of Additional Mathematics, students will be well-prepared for the challenges they will face in their engineering studies and careers.
