In this lesson
In this video you'll learn about algebraic set definitions and subsets (higher) for GCSE Maths, with worked examples and the mistakes examiners report. By the end you'll be able to interpret a set defined by an algebraic condition (e.g. A = {x : x is a natural number, x ＜ 10}) and use subset notation A ⊆ B to state that every element of one set also belongs to another.
By the end: Interpret a set defined by an algebraic condition (e.g. A = {x : x is a natural number, x < 10}) and use subset notation A ⊆ B to state that every element of one set also belongs to another.

On the specification
| Board | Spec | Statement |
|---|---|---|
| Cambridge IGCSE 0580 | E1.2 | Understand and use set language, notation and Venn diagrams to describe sets and represent relationships between sets. |

For teachers
This GCSE Maths lesson teaches algebraic set definitions and subsets (Higher). By the end, students should be able to interpret a set defined by an algebraic condition (e.g. A = {x : x is a natural number, x ＜ 10}) and use subset notation A ⊆ B to state that every element of one set also belongs to another. It works through two worked examples and the mistakes examiners report.
