IGCSE Maths 0580 | Approximation & Accuracy Explained Clearly | From Zero to A★ with Mai Lin

Описание: Welcome back to Mai Lin’s IGCSE Mathematics Fast-Track Series!
In this lesson, we focus on a highly practical and exam-favourite topic in the Numbers chapter — Approximation & Accuracy.

Approximation questions test how well you understand rounding, significant figures, decimal places, and how accuracy affects real-life calculations.
Many students lose easy marks by rounding too early or misunderstanding what a question is really asking.

This video teaches you how to handle approximation clearly, systematically, and safely, exactly the way Cambridge examiners expect.

📘 What You’ll Learn:

What approximation means in mathematics

Rounding numbers to a given number of:

Decimal places

Significant figures

The difference between exact values and approximated values

When and when not to round during calculations

Understanding accuracy in real-life contexts

Common IGCSE exam traps involving rounding

Step-by-step strategies for Paper 1 & Paper 2 questions

How approximation links to estimation, bounds, and measurement

💡 Mai Lin’s Tip:
“Round at the end, not in the middle.”
This simple rule prevents most accuracy-related mistakes in exams.

⚡ Why This Matters:
Approximation & accuracy questions appear frequently in IGCSE Mathematics 0580, especially in:

Real-life problem solving

Measurement-based questions

Multi-step calculations
