Relations and Functions: Part 1

The set theory helps us understand how a collection of like objects behave. Venn diagrams are useful when you have different sets of the same type. However, to work with sets of different kinds, you need to know the concept

Part 2: Venn Diagrams and operations on Sets

For introduction to set theory, see part 1 here To continue our discussion, let’s study Venn diagrams. These are very helpful way to visualize set operations. Let’s start with an example: Let there be two sets A and B such

Part 1: The Set Theory (basics)

Sets Our solar system has 8 planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Neptune and Uranus. They all have one feature in common: they  are relatively big round objects that revolve around the Sun. We all have agreed upon this
