What this calculator teaches
Convert a small edge list into an adjacency matrix and adjacency list.
Discrete mathematics is the foundation for logic, algorithms, data structures, graphs, combinatorics, and many computer-science topics. These calculators are designed to support learning rather than replace reasoning.
Formula & Symbols
| Concept | Formula or rule |
|---|---|
| Adjacency matrix | Mᵢⱼ = 1 if there is an edge from node i to node j. |
| Adjacency list | For each node, list its neighbors. |
Worked Example

When to use it
Common mistakes
Enter only the elements or pairs requested. Avoid extra words unless they are part of the element names.
Discrete math often depends on empty sets, repeated items, self-pairs, and direction. Check these carefully.
A calculator can check examples, but proofs require explaining why the rule works for all valid cases.
