  Depending on the calculator, you may receive a single answer, a series of values, or a truth table. Carefully study the output to understand the solution to your problem.

What Does Discrete Mathematics Mean?

Discrete Mathematics is a branch of mathematics that studies discrete (as opposed to continuous) objects and structures. This means that it focuses on things that can be clearly divided and counted, rather than things that flow or change smoothly.

Applications of discrete mathematics are vast and can be found in computer science, statistics, operations research, and many other fields. Because of its applicability to real-world problems, especially in computer science, discrete mathematics is critical for anyone interested in algorithms and data structures.

What Calculators Does eMathHelp Offer?

Combinations and Permutations Calculator

• Concept: Combinatorics is a branch of discrete mathematics that involves counting, arranging, and selecting objects. This calculator assists in calculating combinations and permutations, which are fundamental in various scenarios, including combinatorics and probability problems.

• Formulas:

  • Permutations without repetitions: $$$P(n,r)=\frac{n!}{(n - r)!}$$$
  • Combinations without repetitions: $$$C(n, r)=\frac{n!}{r!(n - r)!}$$$
• Example: Suppose you have 5 different books and you want to find the number of ways to arrange 3 of them on a shelf. You would use the permutations formula to find that there are $$$P(5, 3)=60$$$ ways to arrange the books.

Truth Table Calculator

• Concept: Truth tables are used in logic to display all possible combinations of inputs and the resulting outputs for a given boolean expression. This calculator generates truth tables, helping you analyze the behavior of logical circuits and expressions.
• Formulas: There isn't a specific formula for truth tables, but they are generated based on the logical expressions provided.
• Example: Suppose you have a logical expression $$$a\wedge\left(b\vee\neg c\right)$$$. The truth table calculator will create a table showing all possible combinations of $$$a$$$, $$$b$$$, and $$$c$$$, as well as the result of the expression for each combination.

Boolean Algebra Calculator

• Concept: Boolean algebra is a branch of mathematics that deals with binary variables and logical operations. This calculator allows you to work with boolean expressions, perform AND, OR, NOT, and XOR operations, and simplify complex boolean expressions.

• Formulas:

  • AND operation: $$$A\wedge B$$$
  • OR operation: $$$A\vee B$$$
  • NOT operation: $$$\neg A$$$
  • XOR operation: $$$A\oplus B$$$
  • Boolean expression simplification rules, such as De Morgan's laws and distribution laws.
• Example: You have the boolean expression $$$\left(A\wedge B\right)\vee\left(A\wedge C\right)$$$. You can use the calculator to simplify it to $$$A\wedge\left(B\vee C\right)$$$ for easier analysis.
