When this property is set to true, the user can press the equal sign key to type, display, or make modifications to formulas in cells. Even if this property is set to false, you can still provide formulas for cells programmatically using the Formula property (in the Cell, Row, or Column object). This property simply prevents users from entering formulas.
For more information on formulas, refer to the Formula Reference.
