Shelly and Sam love to go deep sea fishing for swordfish.  Each time they go deep sea fishing, Shelly catches 2 less than five swordfish, and Sam catches one less swordfish than Shelly.  If Sam and Shelly go fishing 5 times, how many swordfish do they catch in total?
Shelly catches 2 less than five swordfish each time they go fishing, for a total of 5-2=<T>subtract(5, 2)=3 fish per trip.
Sam catches one less swordfish than does Shelly on each trip, or a total of 3-1=<T>subtract(3, 1)=2 swordfish per trip.
Together, they catch a total of 3+2=<T>add(3, 2)=5 swordfish on each trip.
If Sam and Shelly go fishing 5 times, they catch a total of 5*5=<T>multiply(5, 5)=25 swordfish.
