Title: NOT A PERFECT METHOD AFTER ALL!!!!
Product review: What this book has is an interesting way to solve problems but I found that using bill handley method. Is wrong and has an error. 8x3=19 using his method. Because 10 is your referance number and you put a negative 2 under 8 and negative 7 under 3 they are negative beacuse there under the numbers of 8 and 3. You add diagonaly to get (8+(-7)) or (3+(-2)) they both equal 1. 1x10=10 multiply the referance number to 1.Then you add the bottom numbers as a positive numbers to get 7+2=9. 10+9=19. Anyone could figure it's 24. Don't depend on his ability because it's not perfect!! look for a different book!!!!
