Word always suggests a formula based on the position of the active cell when the command is issued. This formula is rarely what is really needed. Just erase it to build your own. All formulas must start with an equals sign. After this, formulas are composed of three parts:
Common mathematical operators such as +, -, *, and /.
Special procedures provided by Word. Functions always appear outside parentheses.
