    RPNCalc - The command line Reverse Polish Notation (RPN) Calculator

    RPNCalc is the command-line based Reverse Polish Notation (RPN) calculator. RPN calculators make it very simple to do complex calculations, especially if there are parentheses involved. I've created a User Guide (https://frossm.github.io/RPNCalc-UserGuide) to do a better job of explaining how to use RPNCalc than the old readme.md file, which was getting really long. If you have questions, issues, feedback, or ideas, please let me know. You can contact me via the links in the **Introduction** page of the User Guide. ## RPNCalc User Guide: https://frossm.github.io/RPNCalc-UserGuide ##

    Logic Calculator

    A Calculator to perform logical operations

    The Logic Calculator is an application useful to perform logical operations. It has three modes: (1) Evaluation of logic formulae: In this mode we have the basic boolean operations (negation, conjunction, disjunction, conditional and biconditional) so the user can insert the logic formula and the Logic Calculator displays the truth table along with the models of the formula. (2) Logical entailment: In this mode the user can insert a number of premises followed by a number of conclusions, so the Logic Calculator displays the truth table of each premise / conclusion and the result of whether or not these premises logically entail the given conclusions. (3) Conversion of a formula to Disjunctive Normal Form (DNF) and Conjunctive Normal Form (CNF): In this mode the user inserts a logic formula and the Logic Calculator outputs its representation in both a DNF and CNF.
