## Truth Table

### A truth table is a table used to represent the different possible truth values (true or false) of a logical statement or proposition

A truth table is a table used to represent the different possible truth values (true or false) of a logical statement or proposition. It outlines all the possible combinations of truth values for the variables involved in the statement and shows the resulting truth value of the statement for each combination.

In a truth table, the rows represent the different combinations of truth values for the variables, and the columns represent the variables and the resulting truth value of the statement. The number of rows in a truth table is determined by the number of variables involved. Each row in the truth table corresponds to a unique combination of truth values for the variables.

To create a truth table, you start by listing all the variables involved in the statement. Then, you write down the number of rows needed based on the number of variables. For example, if you have n variables, you will have 2^n rows.

Next, you fill in the truth values for each combination of truth values. This is done systematically by writing down the possible values for each variable in each row, proceeding from left to right. For example, if you have two variables A and B, each with two possible truth values (true or false), you will have four rows, representing the four combinations: (A=true, B=true), (A=true, B=false), (A=false, B=true), (A=false, B=false).

Finally, you determine the resulting truth value of the statement for each combination. This can be determined using logical operators such as AND, OR, and NOT. The resulting truth value is typically written in the last column of the truth table.

By examining the truth table, you can analyze the logical behavior of the statement and determine its truth or falsity based on the truth values of the variables.

Truth tables are extensively used in logic and boolean algebra to evaluate logical statements, determine tautologies (statements that are always true), and perform logical reasoning and deductions.
