​What I Need to Know

The module contains lessons on:

​

  • Lesson 1 – Sets

​  • Lesson 2 - Subset, Universal Sets, Null Set, Cardinality of Sets

​  • Lesson 3 – Union and Intersection of Sets and the Difference of Two Sets

​After going through this module, you are expected to:

1. define a well-defined set;

2. illustrate a subset, universal set, null set, cardinality of set; and

3. analyze union, intersection, and the difference of two sets

​SETS

​The groups are called sets. Set maybe thought as a collection of objects.
