Thanks all for some valid comments. It is true that the book was not especially written for gifted children ..

Most of the 55 rules are basic math truths but written (with examples) for improved understanding by those that need it ...
Nothing particularly unique about them ! but they are needed to understand the math validity of the unique Word/Fraction technique

However, I wonder if any readers took the time to read the website's tab called 'WORD/FRACTION TECHNIQUE'. Please try the example problem on your gifted students (review their writings..
% correct)

Here is a summary of a technique which I believe is both unique and effective for those that the many that have difficulty.

1. No arithmetic until the equation is written !!! (see below)

2. Word/Fractions (W/F)can be inverted at will
(60 miles/hour = hour/60 miles)

3. Conversion W/F (3 feet/yard) (all equal to 1 may be added as
as a product in the equation)

4. Step # 1 in creating the equation is to write down the name of the answer ( = ? miles/hour)

5. Write an equation using a data from the problem (mostly products) ...(which is probably incorrect initially)

^. Using dimensional analysis, invert any or all W/F in order to cancel all words (as NUM/DEN pairs) on the left side equation until the remaining words equal the answer name.

Comments of the above basic concept of the book is welcomed (e.g. why it is not an improvement to any existing methods, if there any overall detailed methods)

Your comments are getting closer but still pretty general with no comments on the W/F and that MWP are a problem due to reading ,etc.
