Design smart PDF forms with calculation functions using Adobe Acrobat

Adobe Acrobat allows users to create interactive PDF forms with calculation functions, eliminating the need for printing and reducing errors. This feature is useful for documents like invoices, enabling automatic calculations such as addition and subtraction directly within the PDF. Users can prepare documents in any text editor or Acrobat, then use the "Prepare a Form" tool to add fillable fields and define calculation properties for specific fields.
