Magnificent Mistakes in Mathematics
“[F]or me it is the mathematical gaffes the rest of us are more likely to fall for that make Posamentier and Lehmann's book interesting. My favourites are the proofs that involve dividing by zero, leading to results such as 1=2.” -New Scientist  “This volume could be useful to a teacher of mathematics as a source of examples that can hammer home important concepts.”-Library Journal “Don’t be scared off by the ‘mathiness’… Magnificent Mistakes in Mathematics is an intriguing read. I’ll bet that even old hands at mathematics will find something new here… a great opportunity as the school year begins, giving us a chance once again to ‘go figure!’” -Astro Guyz“A fairly quick and entertaining read for typical math buffs… I think this somewhat unique approach makes the volume a worthwhile, entertaining addition to one's math bookshelf, and it may be particularly useful to secondary school teachers, providing a lot of grist for instructive, thoughtful examples in the classroom.”-MathTango “Advanced math skills are not required to enjoy untangling errors that illustrate concepts in arithmetic, algebra, and more.”           -Science News
