Entering over-under fractions can be a nightmare. Whenever possible, use a slant line or negative exponent to signify division. Change the format to a single line, like this: (O — E)2/E 2. If a really complex formula cannot be avoided, consider treating it like a figure. Furnish it in the form of a line drawing. Fractional exponents (X0'5 ) may also be used instead of square root and cube root signs (Swanson et al., 1999).


When writing or editing a typescript, one is confronted with a potpourri of grammatical and rhetorical writing flaws rather than neatly categorized sets such as those presented in a writing book or style manual. The "test" that follows is given as an opportunity for practice of this slightly more realistic sort.

We hope that one of the messages you have received from this book is that more than one way of revising is always possible and almost always acceptable. As always, judge your choices not only by correctness, but also by their clarity, brevity, readability, and communicative power.
