The mathability of spreadsheet tools

In the present paper, we compare low and high mathability level spreadsheet tools. Firstly, we provide proof that the widely accepted and practiced surface approaches are responsible for error-prone spreadsheet documents. In addition to this, we introduce Sprego, and demonstrate that it is a high mathability level method. We provide examples of how spreadsheets are programmable with Sprego, how the concepts and the algorithms can be built specifically for the problems involved, and how they can be discussed and debugged. In general, we give evidence to show how spreadsheets serve as functional languages, and as such are high level mathability tools.
