Notation for Simple proposition and

ConnectiveLets try to write it

Notation is a system of written symbols. Simple proposition can be written through a

notation to show the essentials of proposition

Basic concept

Simple proposition has just one predicator which is written in capital letters

The arguments of the predicator are represented by single lower case letters, putting one of these letter before the predicator and after the predicator (if there are other predicator)

How to write the notation

The element such as forms of the verb be, article, tense marker and certain preposition are omitted.

Preposition which make no contribution to the sense of a sentence are omitted and vice versa

Two word verbs such as look-for, turn down and switch on are treated as single predicates

John died j DIE Romeo loved Juliet r LOVE j George was a nephew of Alice g

NEPHEW a

Examples:

Is a sentence to declare that two referring expression found in the sentence have the same referent. ◦ Example :

Venus is the morning star

Equative Sentence

Use “=“ to represent the verb be Example : Obama is the president of USA o = p Venus is the morning star V= ms

How to write the notation of equative sentence

1. j LOVE m Jim loves Mary 2. c story Cinderella is a story 3. aw = artist Ari Wibowo is an artist

Is it a well-formed notation ?

It is used to make complex propositional formulae by connecting simple propositional formulae◦ Example :

Wayan loves Ina and Ani (w LOVE i) & (w LOVE a)

Kunti was Bima’s mother or Gatotkaca’s grandmother and Duryudana’s aunt (k MOTHER b) V {(k GRANDMOTHER g) & (k AUNT d)}

Connective : “And” (&), “Or” (v)

1. Bob will take Lucy, Cory and Diana 2. Either Bangkok or Chiang Mai is the

capital of Thailand 3. Japan and Dutch colonized Indonesia

Can you make the notation ?

If you have any questions, leave it to my email or we will discuss it next week.
