DropCalc – You have to count with it!
How often did it happen that you would have needed a previous partial result? Calculators usually have memory functions, but how does this MR+/MR- function actually work? Would it not be easier to set aside the results and, if needed, return it to the calculation?
By using DropCalc you can set the partial results aside with an single step, and return them in the same way, whenever you want!
Complicated, paper-based calculation? Forget it, you are at one touch ahead of a much more comfortable solution!
Try it for yourself!
