说明
Built for Discrete Math and Discrete Structures courses, Discretica focuses on the topics students actually need for homework, quizzes, and finals: truth tables, direct proof, proof by contradiction, induction, set theory, combinatorics, graph theory, logic gates, modular arithmetic, GCD, LCM, and base conversion.
Interactive discrete math tools
- Truth table builder: Generate truth tables for logical expressions with AND, OR, NOT, implication, biconditional, and step-by-step connective evaluation.
- Set operations: Work with union, intersection, difference, symmetric difference, power sets, cardinality, and Venn diagrams.
- Combinatorics calculator: Solve permutations, combinations, factorials, and stars-and-bars problems with clear breakdowns.
- Modular arithmetic: Compute modular addition, subtraction, multiplication, exponents, and inverses with worked steps.
- Base converter: Convert numbers between binary, octal, decimal, and hexadecimal using positional notation.
- GCD and LCM calculator: Follow the Euclidean algorithm, extended GCD, and Bezout coefficient steps.
- Proof trainer: Practice direct proof, contradiction, contrapositive, and induction with guided proof exercises.
Complete course coverage
1. Logic and propositions: truth values, connectives, truth tables, equivalences
2. Proof methods: direct proof, contradiction, contrapositive, induction
