Which implies symbol

Improve this question. Imagine an equal sign just as long as the long arrow. Would you be accepting it as a relational symbol? CharlieParker I think you need 'amsmath' — jamaicanworm. Add a comment.

Sometimes the implication operator has lower precedence than other things around it, and in such cases, a giant double-wide arrow looks silly. Example: math. CharlieParker: you need the amsmath package for that.

Mathematical logic is a subfield of mathematics exploring the applications of formal logic to mathematics. It bears close connections to metamathematics, the foundations of mathematics , and theoretical computer science. Logical reasoning is the process of using a rational, systematic series of steps based on sound mathematical procedures and given statements to arrive at a conclusion.

Symbolic Logic. Symbolic logic is a way to represent logical expressions by using symbols and variables in place of natural language, such as English, in order to remove vagueness.

Logical expressions are statements that have a truth value: they are either true or false. The logical OR symbol is used in Boolean algebra to indicate an inclusive disjunction between two statements.

An inclusive disjunction is true if either, or both, of its components are true. In logic : Logical notation. The way in which logical concepts and their interpretations are expressed in natural languages is often very complicated.

In order to reach an overview of logical truths and valid inferences, logicians have developed various streamlined notations. Not equal. In LaTeX, this is done with the " eq" command. The concept of logical operators is simple. They allow a program to make a decision based on multiple conditions. Each operand is considered a condition that can be evaluated to a true or false value.

Then the value of the conditions is used to determine the overall value of the op1 operator op2 or!
