Frankie Pickle and the Mathematical Menace by Eric Wight

4.0

Frankie Pickle is back and better than ever. After turning the numbers into monsters instead of actually completing his math quiz, Frankie embarks on a weekend of preparation for a make-up test. Numbers come at him everywhere, from the grocery store to a "Yugimon" card game with his friend Kenny. Obviously, the appeal of these stories mostly come from Frankie's imagination-fueled adventures.
