Question 38

Rosa has a parrot that does the math in a strange way. Every time Rosa says two numbers he does the same count. For example: - If Rosa says "4 and 2" the parrot responds "12"; - If Rosa says "5 and 3" the parrot responds "12"; - If Rosa says "3 and 5" the parrot responds "14"; - If Rosa says "9 and 7" the parrot responds "24"; - If Rosa says "0 and 0" the parrot responds "1". If Rosa says "1 and 8" what does the parrot respond?
