John buys a lightsaber toy.  It is twice as expensive as all his other Star Wars toys combined.  If his other Star Wars toys cost $1000, how much money has he spent in all after buying the lightsaber?
The lightsaber cost 1000*2=$<T>multiply(1000, 2)=2000
So he has spent 2000+1000=$<T>add(2000, 1000)=3000
