At Hank’s cafe, he sells big stack pancakes which have 5 pancakes and short stack pancakes which have 3 pancakes.  If 9 customers order the short stack and 6 customers order the big stack, how many pancakes does Hank need to make?
For the short stack orders, Hank needs to make 3 x 9 = <T>multiply(3, 9)=27 pancakes.
For the big stack orders, he needs to make 5 x 6 = <T>multiply(5, 6)=30 pancakes.
Altogether, Hank needs to make 27 + 30 = <T>add(27, 30)=57 pancakes.
