Why it’s so important to calculate with sets ?

• Some calculations are not defined with numbers but have a result with sets :
• and depending on which set, the operation / is difined.
• Computer Operating Systems return an error for such calculations. Thus we could think that consequences are similar. But interpretations are very different.
• No result in the first case.
• Many results or an infinity of results in the second case, a really tricky case to interpret, depending of the set, calculus accuracy, ... :
• calculus accuracy,
• set nature,
• ...
• The use of Set Calcul would force to evaluate more interpretations.
