The negation of the statement:
p: a + b = b + a is a true for every real number a and b.
~p: There exist real numbers are ‘a’ and ‘b’ for which a+b ≠ b+a.
The statement is not the negation of the first statement.
Check whether the following pair of statements is a negation of each other. Give reasons for your answer. (i) a + b = b + a is true for every real number a and b. (ii) There exist real numbers a and b for which a + b = b + a.
