+### ✳️ Discrete Mathematics
+
+A common subject that is taught for Computer Science Students and Some Math/Electrical Engineering Majors based on the Assoication For Computing Machinery Guidlines for CS/CE education. Discrete Mathematics presents the most essential subjects for _abstract mathematical modelling_ and _theory of computation_. _Discrete Mathematics_ is a multi-semester course that involves subjects about the theoretical basis of computer science, including but not limited to:
+* Logic (Propositional, Quantificational and Normal Forms).
+* Axiomatic Set Theory (Sets, Operations on sets, and Power Sets).
+* Relation Sets and Function Theory (i.e., $$\Lambda$$ Calculus).
+* Theory of combinatorics.
+* Matrix and Graph Theory.
+* Theory of computation (i.e., Computational Automata Theory, Computational Complexity, and Computational Computability).
+* Automata Theory (e.g., Finite-state Machines, Pushdown Automata, Turing Machines, and Cellular Automata).
+* Process Modelling/Calculi (i.e., $$\Pi$$ Calculus).
+* Coding Theory.
+* Division Theorem Modular Arithmetics (Parts of Number Theory).
