Jack has 42 pounds, 11 euros, and 3000 yen. If there are 2 pounds per euro and 100 yen per pound, how much does Jack have in yen?
First convert the euros to pounds: 11 euros * 2 pounds/euro = <T>multiply(11, 2)=22 pounds.
Then add that amount to the amount Jack has in pounds: 22 pounds + 42 pounds = <T>add(22, 42)=64 pounds.
Then convert the pounds to yen: 64 pounds * 100 yen/pound = <T>multiply(64, 100)=6400 yen.
Then add that amount to the amount Jack has in yen: 6400 yen + 3000 yen = <T>add(6400, 3000)=9400 yen.
