What is a logical formula?

An expression in the language of formal logic.

What is a main connective in logic?

What does V stand for in logic?

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.
