Examples for

Discrete Mathematics

Discrete mathematics deals with areas of mathematics that are discrete, as opposed to continuous, in nature. Sequences and series, counting problems, graph theory and set theory are some of the many branches of mathematics in this category. Use Wolfram|Alpha to apply and understand these and related concepts.


Use the ideas of permutation and combination to find binomial coefficients or integer partitions or to do other forms of counting.

Compute binomial coefficients (combinations):

Compute a Frobenius number:

Point Lattices

Compute the properties of these discrete subsets of Euclidean space. Deal with regular or rooted lattices. Compare them.

Ackermann Function

Work with the famous function known for being a total computable function that is not primitive recursive.

Evaluate the Ackermann function:

Graph Theory

Work with known graphs or specify your own via adjacency lists. Check for isomorphism, compute the shortest path and more.

Compute the properties of a named graph:

Compare several graphs:

Analyze a graph specified by adjacency rules:
