Creating equations
Equation Editor lets you insert preset equations or you can also build your own equation by inserting preset templates and symbols.
Symbols are single characters, such as logic symbols and Greek characters. A template consists of a symbol and, in some cases, writable areas, or slots, for adding variables or other elements. For example, a fraction template provides two slots, one for the numerator and one for the denominator, that are separated by a line (
). You can insert these equation elements by choosing them in Equation Editor or by using shortcut keys.
Each equation you insert into a document is treated as one item rather than individual symbols or characters. The equation is inserted into a document inside a graphics box, which you can move, size, and edit. For more information about formatting a graphics box, see “Inserting graphics boxes and text boxes.”
