A simple process template is usually applied to each problem:
*Select relevant trick/s.
*Use a ‘Test of Reasonableness’ to correct for any decimals.
This really is practical and by positive feedback after each set of exercises, and encouraging comments from the author, will spur the reader to finish every trick. One weakness would be a rote memory approach, so when confronted with a different problem a student may be left floundering.
To get the most out the book the reader should prove each of the techniques using basic algebra.
The book is a great complement to others in this genre.
The only drawback to this book is that with the advent of cheap prolific calculators, there is no need for archaic fractions in our dismal oriented world.
This may not be the be-all-end-all on the subject but I found it helpful from the grocery store to the IRS.
