Did you ever struggle with the standard calculator because you did a mistake and you have to do the whole calculation again? Here’s a nice alternative that solves this issue : CalcTape
CalcTape will let you correct any operation or number directly. You can see every part of your calculation and you can even write text to explain the calculation.
This calculator includes just basic operations, but they are more then enough for most of our calculations. You can copy the entire text into the clipboard to paste where you want.
In the settings page you can setup few preferences like Round behavior, decimals, indentation, etc.
I personally prefer this calculator over the standard one because you can see the operations and correct them.
