Statement

Mathematics

Not quite remember

I easily remember

A statement

Suatu ayat yang dapat ditentukan nilai kebenarannya, iaitu sama ada benar atau palsu, tetapi bukan kedua-duanya

x ∈ R means x is an element of the real numbers

Real numbers can be defined as any rational numbers or irrational numbers

Not all the mathematical statements are true

The truth values of the mathematical statements can be determined

We use the word “no” or “not” to negate a statement

The negation of statement p is written as ~p. ‘~p’ is read as ‘tilde p’

The process of negation

The truth values change from true to false or vice versa

A statement “if p, then q” is known as an implication

• p is denoted as the antecedent • q is denoted as the consequent

Two implications of “p if and only if q”

• if p, then q • if q, then p

Statement : If p, then q. Converse : If q, then p.

Inverse : If ~p, then ~q. Contrapositive : If ~q, then ~p.

The truth value of an implication “if p, then q” is always true except when p is true and q is false happen at the same time

If an antecedent is false, then the implication “if p, then q” is always true without depending on the truth value of the consequent
