Error in the Technological Resources Used for Mathematics Education

In order to encourage the use of spreadsheets in everyday school life, more precisely in mathematics teaching, we have searched, over the course of more than a decade, for the applicability of these tools in the classroom. As we have applied fundamental properties of mathematics to the teaching and learning process, we have found, to our surprise, that bluntly, the spreadsheet makes errors in the process of solving certain activities. In our research to date, dozens of errors in applying the spreadsheet to solve activities have been recorded. So we may ask ourselves, why is this spreadsheet software still being marketed worldwide? In view of so many primary errors with catastrophic results already listed by these researchers, in different areas such as: health, economy, business, education, military among others, why don’t the companies that own this software, charging abusive amounts in licenses to their users, make the necessary corrections in the computer programs
