Now prove the statement using a proof by contradiction. Statements to choose from: Your Proof: Put chosen statements in order in this column. Let a and b be integers and assume that Let a and b be integers and assume that if a + b is odd, then either a or b is odd. a +b is odd but a and b are both even. Let a and b be integers and assume a + b is odd. The sum of two even integers must also be even. Let a and b be integers and assume both are even. Therefore a + b is even. But then a + b is both even and odd, a contradiction.
