User Testimonial (B.T.):
NME is Phenomenal.  Great application for those crossing over from Calculus to Discrete math, number theory, and Abstract Algebra. I have also perused all of the applications and was thoroughly impressed. This program is a beast, give your programmers a tap on the back for me.  You guys have outdone yourselves with this one. the only thing missing in the repertoire is the Abstract Algebra. (Note: This was added in v2.0 , see below.)  

NEW in Version 2.0
- Collatz
- Perform Wilson's Theorem
- Prime Number Theorem
- Composite Numbers
- Dirichlet Box Principle
- Amicable Numbers
- Divisibilty Criteria
- Abstract Algebra: Fields, Rings, Groups, 
  Homomorphisms, Isomorphisms,  
  Ideals, etc
- Perform Permutation Groups using Matrices
