Title: Updated book, still has serious flaws!!! :(
Product review: Getting to the point, pages 180 & 181 are incomplete!!! the formula is given for the "area" of a circle BUT the examples and answers are NOT complete!!! The area of a circle with radius 3 = PI times 3 squared = 28.26 NOT 9Pi square units!!! This is a very bad example of teaching young students!!! Page 108 "The Pythagorean Theorem" A square + B square = C square!!! Where is the formula shown???? This is the BONE basics of the Pythagorean property and its NOT mentioned.... This is the updated 2010 edition and someone STILL forgot to "proof read" this book... The book is OK but you need the COMPUTER to cross reference and find ALL the mistakes & correct them...
