Santino has 2 papaya trees and 3 mango trees. If each papaya tree produces 10 papayas and each mango tree produces 20 mangos, how many fruits does Santino have in total?
Santino has 2 * 10 = <T>multiply(2, 10)=20 papaya fruits
Santino has 3 * 20 = <T>multiply(3, 20)=60 mango fruits
In total, Santino has 20 + 60 = <T>add(20, 60)=80 fruits
