Henry had some games, and he gave six of them to Neil. Now, Henry has 4 times more games than Neil. If Neil had 7 games at first, how many games did Henry have at first?
After getting six games from Henry, Neil has 6+7=<T>add(6, 7)=13 games.
Now, Henry has 13*4=<T>multiply(13, 4)=52 games.
Henry had 52+6=<T>add(52, 6)=58 games at first.
