Your friends will probably think that CalcTape is some kind of advanced calculator from Microsoft. Very useful feature that CalcTape has would be the fact that it has tabs, so users can manage several calculations at once, each one having its own tab. Calculations can even be saved and continued later, which is great for all those who are working on long equations. Some of the more interesting features that CalcTape has would be:

  • Adding machine type of overview over calculation terms
