Edexcel Maths Specification B (4MB1): Lecture 3 - Number Types, Unit Conversions & DST Formulas

Welcome back to Lecture 3 of our Edexcel Maths Specification B (4MB1) series. We are continuing our journey through the Number unit. While some of these concepts may seem basic, they are mandatory parts of the specification that can account for up to 8% of your total exam marks—the difference between an A and an A*! In this video, we break down the classification of numbers and master the specific unit conversions you will face in your O-level papers. We also bridge the gap between Math and Physics by covering the Distance-Speed-Time (DST) formulas essential for high-mark Paper 2 questions. What you will learn in this lecture: Number Classification: Natural numbers, Integers, and a deep dive into Rational vs. Irrational numbers. Rational Scenarios: Why recurring decimals and integers are always rational. Irrational Proofs: Understanding pi and the square root of 2 as defined, non-fractional values. Mandatory Unit Conversions: Length (km, m, cm, mm), Mass (kg, g), and Volume (L, ml). Time & DST Formulas: Mastering Speed = Distance / Time and its variations for exam word problems. Currency Exchange: How to handle exchange rates using basic proportional math.
