Is this a better way to define "Spreadsheet"?

Dictionaries, encyclopedias, textbooks, etc define spreadsheets for adults - in terms of large tables of facts and figures about business enterprises. To me a spreadsheet is software you can use in basically three ways:(a) like a piece of paper (b) like a hand-held calculator and (c) like a programming language. This greatly frees up what you can do with spreadsheet programs as "Mindtools" , particularly in the elementary clroom.
