A basic calculator supercharged to handle a whole slew of Number Theory operations. What would normally take you hours doing homework to find the Phi or Sigma of a number will now take a few taps. Work with Integers (Foundational to Number Theory) or sets of IntegersThe list of included algorithms is not conclusive of all Number Theory algorithms, so if there is something that you need or want to see, leave a nice review or let me know through the my website! A few of the included algorithms: Greatest Common Factor Least Common Multiple Factorization Is a Factor Proper Factors Is a Prime Is it Relatively Prime? Set/Array Functions Sigma Phi Exponents Congruencies Carmichael Numbers Is Triangular Is Square Is Pentagonal AND MANY MORE!
