What kind of statement is P → Q?

Prove or disprove: for any mathematical statements p,q and r,p→(q∨r) is logically equivalent to ¬r→(p→q).

What is a symbolic statement in math?

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.
