 Create 3 and 4level binary trees automatically
 Demonstrate, stepbystep, Depth First and Breadth First Searches
Matrices
 Create multiple matrices with any number of rows and columns
 Perform mathematical functions on matrices
 Square or cube a matrix in one click (good for demonstrating Graph concepts)
 Automatically set up matrices such as xij, aij, bij, and identity
Polynomial to Tree
 Create a binary tree in graphical form representing a polynomial
Sets
 Quick set creation
 Demonstrate Union, Intersection, Difference, Equality Subset, Cross Product
Power Sets
 Venn diagrams
Relations and Functions
 Define your own relation or use samples
 Test for Reflexive, Symmetric, Transitive
 Test for function, 1 to 1, Onto
 Inverse of a relation
