Qalculate! is small and simple to use but with much power and versatility underneath. Features include customizable functions, units, arbitrary precision, plotting, and a graphical interface that uses a one-line fault-tolerant expression entry (although it supports optional traditional buttons).

apt install qalculate-gtk

inicie o aplicativo, você verá a seguinte mensagem:
