In symbolic logic, a letter such as p stands for an entire statement. It may, for example, represent the statement, "A triangle has three sides." In algebra, the plus sign joins two numbers to form a third number. In symbolic logic, a sign such as V connects two statements to form a third statement.

What is symbolic logic statement?

By a "statement" in logic one means an assertion which is true or false. One may not know whether the statement is true or false, but it must be one or the other. For example, the Goldbach conjecture, "Every even number greater than two is the sum of two primes," is either true or false, but no one knows which.

Are Biconditional statements always true?

It is a combination of two conditional statements, “if two line segments are congruent then they are of equal length” and “if two line segments are of equal length then they are congruent”. A biconditional is true if and only if both the conditionals are true. Bi-conditionals are represented by the symbol ↔ or ⇔ .
