We have the predicates E and O describing integers, defined by E(n) is true if n is even, and O(n) is true if n is odd.

(a) Express in predicate calculus notation the sentence the sum of two odd integers is even.

(b) Give the negation of the predicate http://img3.imageshack.us/img3/9336/matho.jpg
