Willy has 10 stuffed animals. His mom gives him 2 more stuffed animals for his birthday. After his birthday, if his dad gives him 3 times more stuffed animals than he has, how many stuffed animals does Willy have in total?
After his mom gives him stuffed animals, Willy has 10 + 2 = <T>add(10, 2)=12 stuffed animals
His dad gives him 12 * 3 = <T>multiply(12, 3)=36 stuffed animals
In total, Willy has 12 + 36 = <T>add(12, 36)=48 stuffed animals
