Who needs the system's default calculator anyway?

Also I have to say that I can accept calculators on phones or tablets, because I can lay them on the same plane where I take notes (I develop my ideas on paper first).

Calculators on computers are always clumsy because I have to look at the monitor and then look at the sheet of paper multiple times. On computers either a develop a big program after havind defined the guidelines on paper, or I mostly don't use the calculator there.
