Mathematics must be effective in technical communication

The mathematical equation is truly an element of the engineer´s vocabulary. As such, it is a vital tool in technical communication. To make it an effective tool and to achieve maximum reader comprehension, engineers and editors must observe certain rules. These rules divide logically into the major categories of writing, editing, and layout. All three categories are treated and examples are discussed. The rules are aimed at facilitating the typing task, ensuring accuracy of the mathematical treatment, making the mathematics meaningful and unambiguous, and fitting the equations into the report style. The writer is responsible for the use and accuracy of the mathematics, and the editor is responsible for the clarity and presentation of the mathematics, including accuracy checks, arrangement, and typography. Examples stress how correct use of certain rules by both the writer and the editor can change inaccurate, ambiguous mathematics into accurate, clear mathematics that is understandable and meaningful.
