LetterSet Lab

Interactive Visualizer for Sets, Operations, and Identities

Build intuition about set theory using a constrained universal set (A–Z), user-input words, and interactive Venn diagram interfaces.

Understanding Sets and Set Creation

A set is a collection of distinct objects or elements. In mathematics, we often use uppercase letters to denote sets and list their elements within curly braces, like {A, B, C}. Sets do not contain duplicate elements - each element appears only once. In this activity, we'll work with the universal set containing all 26 English letters (A through Z), and create three subsets from words you choose.

Create Three Sets from Words

Set W1

1. Enter a word:

2. Create a set of letters:

Enter letters separated by commas, spaces, or just type them consecutively

3. Set W1:
