Sir Cumference and Lady Di of Ameter visit the Earl of Fracton at the annual Fracton Faire. Their day is interrupted when they realize that goods are being stolen from the merchants. And then the earl's sheep go missing, too!
The earl decides to use "Fracton numbers" to catch the culprits. After all, outsiders don't know how to read numerators and denominators properly. With the math trap set, will the earl and his friends catch the thieves?
X and Y mark the spot. Xaxon Yellowbeard was the fiercest Viking warrior of his time. Now a map to his hidden treasure lies in the hands of Radius and Per. Together the cousins must decode the strange numbered grid on the map-and figure out the secret of the Viking's X and Y axes.
The castle steward, Edmund Rounds, has a son-Rounds 2-who helps count supplies for Sir Cumference and Lady Di. When Rounds 2 goes to find out whether the travelers he's seen camping in the woods are in need of provisions, he discovers something that sends him running in a beeline back to the castle.
The travelers are Sir Wantsalot and his men! Can Rounds 2 figure out the bow and arrow totals in time to know whether there are enough to defend the castle?...
