During his summer break, Luke catches 2 fish every day for 30 days.  If each fish gives him 2 fillets, then how many fish fillets does he have?
He catches 2 fish every day for 30 days so he catches 2*30 = <T>multiply(2, 30)=60 fish
Each fish yields 2 fillets so he has 2*60 = <T>multiply(2, 60)=120 fish fillets
