In conditional statements, "If p then q" is denoted symbolically by "p q"; p is called the hypothesis and q is called the conclusion. For instance, consider the two following statements: If Sally passes the exam, then she will get the job. If 144 is divisible by 12, 144 is divisible by 3.
A sentence written in symbolic form uses symbols and logical connectors to represent the sentence logically.

Conditional p → q If p, then q, p is sufficient for q, q is necessary for p. p if and only if q, p is necessary and sufficient for q.
p → q (p implies q) (if p then q) is the proposition that is false when p is true and q is false and true otherwise. Equivalent to —not p or q“ Ex. If I am elected then I will lower the taxes.
P ∧ Q means P and Q. P ∨ Q means P or Q. An argument is valid if the following conditional holds: If all the premises are true, the conclusion must be true. Some valid argument forms: (1) 1.
The converse statement is notated as q→p (if q, then p). The original statements switch positions in the original “if-then” statement. The inverse statement assumes the opposite of each of the original statements and is notated ∼p→∼q (if not p, then not q).
symbolic expression (plural symbolic expressions) (computing) A means of representing semistructured data in human-readable text form, mostly composed of symbols and lists and extensively used in the Lisp programming language.

A statement form is a symbolic representation of a compound statement. It consists of statement variables along with logical connectives joining them.
