Title: A disservice to Mario Salvadori
Review: I knew the late Mario Salvadori and have been a fan of his work. This is obviously a hack job with some of his ideas, then his name slapped on the cover to make it saleable. This book is a train wreck: old problems, no math games to speak of, and it reads like an abbreviated middle school textbook. This is a terrible book and an insult to Mr. Salvadori's memory.If you want a genuine math book for middle schoolers, look to Harold Jacobs' Mathematics: A Human Endeavor, which after 40 years is still the best general interest math book with humor and insight.
