Key IGCSE Additional Mathematics 0606 Terms You Should Know
Understanding mathematical terminology is just as important as knowing how to perform calculations. Here are some of the key terms students will encounter in 0606:
- Function: A mathematical relationship that assigns an output to an input according to a defined rule.
- Domain: The set of possible input values for a function.
- Range: The set of possible output values of a function.
- Composite function: A function formed by applying one function to the output of another function.
- Inverse function: A function that reverses the effect of another function.
- Factor theorem: A theorem used to determine whether a particular expression is a factor of a polynomial.
- Discriminant: A quantity derived from the coefficients of a quadratic equation that can be used to determine the nature of its roots.
- Binomial expansion: The expansion of a power of an expression containing two terms.
- Logarithm: The inverse operation of exponentiation.
- Natural logarithm: A logarithm with base e, written as ln x.
- Radian: A unit for measuring angles based on the relationship between the arc length and radius of a circle.
- Trigonometric identity: An equation involving trigonometric functions that is true for all values for which both sides are defined.
- Vector: A mathematical quantity that has both magnitude and direction.
- Magnitude: The size or length of a vector.
- Differentiation: The process of finding the derivative of a function and therefore determining its rate of change.
- Stationary point: A point on a curve where the gradient is zero.
- Maximum: A point or value representing the greatest value of a function within the relevant interval or context.
- Minimum: A point or value representing the smallest value of a function within the relevant interval or context.
- Integration: The reverse process of differentiation, also used to calculate areas under curves.

Learning these terms early can make it much easier to understand questions and recognise which mathematical technique a problem requires.
IGCSE Mathematics vs Additional Mathematics
One of the most common questions students and parents ask is:
What is the difference between IGCSE Mathematics and IGCSE Additional Mathematics?
The simplest answer is that Additional Mathematics extends mathematical knowledge into more advanced concepts and requires students to make stronger connections between different techniques.
| Feature | IGCSE Mathematics (0580) | IGCSE Additional Mathematics (0606) |
|---|---|---|
| Purpose | Develops core mathematical knowledge and skills | Extends mathematical knowledge and prepares students for advanced study |
| Difficulty | Standard IGCSE level | More advanced and demanding |
| Algebra | Core algebraic techniques | More advanced equations, polynomials and functions |
| Functions | Covered at the appropriate IGCSE level | More extensive work with domains, ranges, inverses and composites |
| Trigonometry | Core trigonometric concepts and applications | More advanced trigonometry, identities and radians |
| Calculus | Not a central part of the 0580 syllabus | Differentiation and integration are major topics |
| Vectors | Covered at the appropriate level | Two-dimensional vectors and applications |
| Kinematics | Not a central component | Included through calculus and motion |
| Problem solving | Mathematical application and reasoning | Greater emphasis on combining techniques |
| Progression | Suitable for a broad range of future pathways | Strong preparation for A Level Mathematics and other highly numerate subjects |
Cambridge states that knowledge of IGCSE Mathematics 0580 or an equivalent qualification is assumed when starting Additional Mathematics 0606.
This means Additional Mathematics is generally taken alongside or after a strong foundation in IGCSE Mathematics, rather than as a replacement for it.
The difference is not simply that 0606 contains “harder questions”. Students are expected to work with more abstract concepts and select from multiple mathematical techniques when solving unfamiliar problems.
For students planning to study A Level Mathematics, Physics, Engineering, Economics or other highly numerate subjects, Additional Mathematics can provide useful preparation. Cambridge describes the qualification as providing a smooth transition to Cambridge International AS & A Level Mathematics.
Key Changes
The 0606 syllabus was reviewed and revised for the first examination in 2025, with the revised syllabus applying to the 2025, 2026 and 2027 examination series.
Some of the most important changes are:
1. Indices and Surds are now assumed knowledge
Indices and surds were removed from the specific 0606 subject content.
However, this does not mean students can ignore them. Cambridge states that knowledge of these areas is assumed and that they may still be required when answering questions on other topics.
Students should therefore make sure their IGCSE Mathematics foundations in indices and surds are secure before beginning Additional Mathematics.
2. Coordinate Geometry of the Circle was added
A new topic, Coordinate Geometry of the Circle, was added to the subject content.
This expands the coordinate geometry component and gives students more experience working with algebraic and geometric relationships involving circles.
3. A Dedicated Non-Calculator Paper was Introduced
One of the biggest assessment changes is the introduction of a dedicated non-calculator paper.
For the 2025–2027 syllabus:
- Paper 1: 2 hours, 80 marks, non-calculator
- Paper 2: 2 hours, 80 marks, calculator allowed
Each paper contributes 50% of the qualification.
This means students need to prepare for both calculator and non-calculator mathematics.
Non-calculator preparation should include strong algebraic manipulation, accurate arithmetic, mathematical reasoning and familiarity with exact values and mathematical relationships.
4. More Marks Can Be Awarded for Working
The revised assessment also updated the mark schemes so that more marks can be awarded for working where appropriate.
Cambridge states that this change brings the marking approach more closely in line with other Cambridge Mathematics qualifications.
For students, this reinforces an important exam habit: show your mathematical reasoning clearly rather than writing only the final answer.
5. The Syllabus Content and Guidance Were Refreshed
Cambridge also updated the wording of learning outcomes and added notes and examples to clarify the expected depth of teaching.
The list of formulas and command words was updated, and a new section on mathematical conventions was included.
Students should therefore use resources designed for the 2025–2027 syllabus rather than relying entirely on older materials.
How is IGCSE Additional Mathematics Assessed?
All candidates take two written papers.
| Paper | Duration | Marks | Calculator | Weighting |
|---|---|---|---|---|
| Paper 1 | 2 hours | 80 | Not allowed | 50% |
| Paper 2 | 2 hours | 80 | Scientific calculator required | 50% |
Both papers contain structured and unstructured questions and can assess any part of the syllabus. Candidates are required to answer all questions.
Candidates are eligible for grades A* to E. Grades F and G are not awarded for this qualification; candidates who do not achieve the minimum standard for E receive an unclassified result.
The assessment also places substantial emphasis on both mathematical knowledge and mathematical reasoning. Cambridge allocates approximately 45–55% to knowledge and understanding of mathematical techniques and 45–55% to analysing, interpreting and communicating mathematically.
Conclusion
IGCSE Additional Mathematics 0606 is designed for students who want to move beyond the standard IGCSE Mathematics curriculum and develop a deeper understanding of mathematics.
The course brings together advanced algebra, functions, trigonometry, vectors, coordinate geometry and calculus while placing a strong emphasis on problem-solving and mathematical reasoning.
The revised 2025–2027 syllabus also makes preparation for both calculator and non-calculator mathematics essential. With a strong foundation, consistent practice and a focus on understanding how different mathematical techniques connect, students can approach Additional Mathematics with confidence and build a strong foundation for A Level Mathematics and other advanced subjects.
