1+1=5 and Other Unlikely Additions

For those who think math problems only have one right answer, this playful book offers a surprising number of solutions to 1+1. In one scene, a man and a cat push a wheelbarrow containing a pumpkin and watermelon. "1+1=hundreds?" asks a banner. The reasoning appears on the following page: "1 pumpkin + 1 watermelon = hundreds of seeds!" In another, the sun and moon grin at one another ("1+1=1?"). The explanation: "1 a.m. + 1 p.m. = 1 day!" An energetic and inventive spin on addition. Ages 5–up. (Sept.)
