The equation editor is only available in Word 2007 and not Excel, Powerpoint or other applications. \left and \right can dynamically adjust the size, as shown by the next example:. It is a totally valid question to ask if we can reference an equation with labeling the actual equation, since clearly Latex already knows the equation numbering. Type display equation numbers in Arabic numerals in parentheses flush with the right margin. " It is exceptionally important for equations. When writing a mathematical expression with nested parentheses in Word 2007 using the Equation command, Word often makes the outermost parentheses somewhat larger than other parentheses: The size difference is so small that it may look like an error, and it does not particularly help in seeing the structure of the expression.
