NEGATION (~)
If p is a statement variable, then negation of p, “not p”, is denoted as “~p”
It has opposite truth value from p i.e., if p is true, ~p is false; if p is false,
~p is true.
EXAMPLES
“Ali is not a Computer Science student” then its negation is “Ali is a computer Science student”
“I like my course of Discrete mathematics ”then its negation is “I don't like my Discrete mathematics course”
“2 + 3 is equal to 5” then its negation is “2 + 3 is not equal to 5”
