Write an informal negation for each of the following stateme

Write an informal negation for each of the following statements. For all real number x, if x^2 > 1 then x > 0. for all_n Element Z, if n is prime then n is odd or n = 2. exist a triangle T s.t. the sum of the angles of T equals 200 degree.

Solution

a) There exists a real number x such that x^2 > 1, then x < 0

b) There exists a number n such that n is not prime then n is not even

c) There doesn\'t exists a triangle such that sum of all the angles of triangle is not equal to 200 degrees
