EXAMPLES OF STATEMENTS OR PROPOSITIONS:
  1. Grass is green. == Grass is green is a statement (or proposition) because the sentence is true and its truth value is T.( Because everyone knows that grass is green)
  2. 4 + 2 = 6 == 4 + 2 = 6 is also a statement and its truth value is T.(Because 4+2 is 6)
  3. 4 + 2 = 7 == 4 + 2 = 7 is also a statement and its truth value is F. ( Because we know that 4+2 is 6 not 7).Here you should note that both 2 and 3 are statements although 4+2=7 is mathematically wrong.
  4. There are four fingers in a hand. ==There are four fingers in a hand is also a statement and its truth value is false.
