Preparing for the O-Level Mathematics examinations can feel like stepping into a maze—especially for students who struggle with core concepts, formulae, and problem-solving techniques. Even parents who are eager to help often find themselves stuck, particularly when their child is confused about coin and note values, counting change, or tackling tricky money word problems. These difficulties can lead to frustration, slow progress, and repeated mistakes at home.

However, there is one tool that can transform revision from overwhelming to manageable: the O-Level A-Maths and E-Maths Formulae Sheets. These compact documents distil the most essential formulae from algebra, geometry, trigonometry, calculus, and statistics—all neatly summarised to support students during both revision and in the examination hall.

In this comprehensive guide, we will explore the value of these formulae sheets, how to use them effectively, and why they are vital not only for examination readiness but also for building long-term mathematical confidence.

What Exactly Are the O-Level A-Math and E-Math Formulae Sheets?

The O-Level E-Maths formula sheet and the A-Maths formula sheet are official reference materials provided to students by SEAB (the Singapore Examinations and Assessment Board) during the O-Level examinations. These sheets contain a summarised list of key formulae used across the syllabus, covering topics such as:

• algebraic identities• quadratic equations• trigonometric ratios• area and volume formulae• coordinate geometry• probability and statistics

For A-Maths, the sheet also includes differentiation, integration, logarithms, binomial expansions, and more.

Students sitting for 4052 Mathematics (E-Maths) and 4049 Additional Mathematics (A-Maths) receive these formula sheets to assist with calculations during the examination.

However, here is the crucial point:The formula sheet is only useful if the student already knows how and when to apply each formula.

Why Formula Sheets Matter More Than Ever

As O-Level Mathematics papers become increasingly application-based, students can no longer rely on simple memorisation or rote learning. They must understand mathematical relationships and know how to apply formulae in real-world contexts—particularly in word problems involving money, measurement, rate, area, and change.

This is where many students struggle.

Parents frequently share that:

Their child mixes up coin and note values
They cannot calculate change confidently
They panic when faced with multi-step money word problems
Small misunderstandings snowball into major mistakes
Revision becomes a battle rather than a productive session

By incorporating the systematic use of formula sheets into daily revision, students begin to see connections between different topics. This not only improves examination performance but also builds logical reasoning skills that support everyday numeracy, including money calculations.

What’s Inside the O-Level E-Maths Formula Sheet?

The O-Level E-Maths formula sheet is designed to support students sitting the 4052 Mathematics examination. While it does not replace the need for strong content mastery, it provides a clear framework to guide both revision and examination work.

How to Use the Formula Sheets Effectively

To maximise their benefits, students should not wait until examination day to familiarise themselves with the formula sheets. Instead, they should integrate them into their revision strategy early on.

Here is a proven method:

Step 1: Print the O-Level E-Maths and A-Maths formula sheets

Keep them visible during study sessions so students become familiar with where each formula is located.

Step 2: Annotate the sheets

Add notes, worked examples, or colour coding to highlight how and when each formula is used.

Step 3: Practise retrieving formulae

Time students as they locate specific formulae. This builds speed and fluency.

Step 4: Apply formulae immediately

Complete practice questions straight after locating the relevant formula to reinforce understanding.

Step 5: Practise without the formula sheets

Alternate revision sessions in which students attempt questions from memory. This helps ensure long-term retention.

Step 6: Review common mistakes

Particularly for money-related questions, track recurring errors and annotate the relevant formulae accordingly.

How to Use the Formula Sheets Effectively

Parents may not realise that strengthening familiarity with mathematical formulae can indirectly enhance practical numeracy. As students become more confident with numbers, algebra, and percentages, everyday money calculations feel far less intimidating.

Formula sheets provide a clear structure for understanding numerical relationships and patterns—skills that are directly transferable to real-life, money-related situations.

If your child is struggling with money concepts such as values, change, or multi-step word problems, reinforcing their foundational numeracy through regular E-Maths and A-Maths formula practice is one of the most effective ways to support them.

A strong grasp of formulae today becomes a lifelong advantage tomorrow.

Parents of Secondary students often tell us they’re worried because their child is struggling to keep up with the faster pace, heavier workload, and increasingly complex problem sums in school. That’s exactly why AGrader’s Secondary Math Programme was created — to give students the structured, step-by-step support they simply cannot get from school alone.

Our weekly lessons follow the latest MOE syllabus and are taught ahead of what schools cover, so your child gets to revise, practise, and clear doubts before each topic appears in class. This early exposure boosts confidence and prevents the common “snowballing” of weak foundations.

What’s Inside the O-Level E-Maths Formula Sheet?

Students learn through clear explanations, proven problem-solving strategies, and high-quality worksheets curated in-house. These include school-style questions and exam-focused problem sums that strengthen key areas such as algebra, geometry, number patterns, graphs, and real-world applications—going beyond memorisation.

To further support learning, our EverLoop Improvement System provides free after-class revision, video walkthroughs, and targeted practice to close learning gaps quickly and effectively.

If you want your child to approach Secondary Math with confidence instead of anxiety, AGrader offers a practical and proven way to build strong foundations, stay consistent, and be exam-ready.
