“The tongue-in-cheek humor combined with Lichtenheld’s wonderfully personified cast of characters makes this a book kids will reach for again.”

“Visual jokes and graphic elements keep this mathematically accurate book humming with humor.”

“With cartoon energy and amusing visual asides, this story does for numbers what Laurie Keller did for states, and that’s saying something.”

“This tale not only reinforces mathematical principles, but also has a great message about friendship and personal feelings.”
