Summary: Develop mathematical reasoning and lateral thinking
Review: My personal opinion is that the book is great. I enjoyed it immensely.Required math skills are minimal--the book shines in how it requires you to combine +, -, x, and division. It's variety ensures you don't settle into a comfortable pattern. Sometimes you have to treat letters as numbers (A=1, B=2, etc), sometimes you have to treat them as symbols with straight lines (e.g. A, E, etc.) or curves (e.g., O, C, etc.), and sometimes you have to treat them as vowels or consonants. Some problems throw in a variety of textures and shapes to throw you off, whereas all you need to do is just count the shapes. All these obstacles serve to teach you to think truly laterally and always be alert. Most problems provide as a starting point some series, table, diagram, etc., and require you to identify a pattern, and complete missing blanks with numbers, letters, or shapes. This book is an excellent preparation for the mathematical portions of an IQ test.
