Connectors in Mathematical logic

 We can make compound statements by connecting 2 or more simple statements .  The main connector that we use to make a compound statement are

  • Negation (NOT) ~
  • Conjunction (AND) ^
  • Disjunction (OR)
  • Conditional (if..then) ->
  • Bi conditional (if and only if (iff)) <->

What is Proposition in Mathematical logic?

A Proposition or Statement is a sentence which has truth value(true/false)
eg: sun rises in the east(T)
      earth is round in shape(F)

Sentence which are not propostion are
eg: what is your name?
      please give me 5 rupees
      shut your mouth
      what a beautiful flower it is!
    
commanding statements, exclamation, questions, request statements are not propostion.
