Conducting with logical reasoning or proof. Solve the question below.. Two mathematicians are talking. The first asks the second about the ages of his/her three children. The second replies "Their ages multiplied together is 36." The first says that is insufficient information. The second replies "their ages add up to the house number you see across the street." The first says that this is still insufficient information. The second then replies that the oldest child is visiting his/her grandparents. The first mathematician then says that they know the ages of the children. How old are the three children? (All ages are whole numbers)
