Mathematical and chemical formulas may be typed or hand-lettered, but must be consistent in style and placement throughout the text. Long, complex mathematical and chemical equations should not be included in text lines, but should be placed in proper position in the center of the page between lines of the text. The lines in structural chemical formulas and hand-lettered mathematical formulas must be drawn with black, permanent (non-water soluble) ink in a neat, professional manner.
All formulas and equations (like all tables and figures) must be given an Arabic number and a caption, placed within the margins. Also, a LIST OF FORMULAS AN EQUATIONS should be added to your front matter and to your table of contents immediately following the LIST OF FIGURES or LIST OF ILLUSTRATIONS whichever is last, and preceding any list of abbreviations or terminology.
