Qalculate! is an arbitrary precision cross-platform software calculator.[8] It supports complex mathematical operations and concepts such as derivation, integration, data plotting, and unit conversion. It is a free and open-source software released under GPL v2.

Features

Qalculate! supports common mathematical functions and operations, multiple bases, autocompletion, complex numbers, infinite numbers, arrays and matrices, variables, mathematical and physical constants, user-defined functions, symbolic derivation and integration, solving of equations involving unknowns, uncertainty propagation using interval arithmetic, plotting using Gnuplot, unit and currency conversion and dimensional analysis, and provides a periodic table of elements, as well as several functions for computer science, such as character encoding and bitwise operations.[9] [10] [11] [12] [13] [14] [15] [16] [17]

It provides four interfaces: two GUIs, one using GTK (qalculate-gtk) and another using Qt (qalculate-qt), a library for use in other programs (libqalculate), and a CLI program for use in a terminal (qalc).

Also, qalculate-gtk (although I understand that you might prefer the CLI) allows you to see the parsed expression as you type and makes it easier to switch between modes. I agree that an alternative mode along the lines of your suggestions might be beneficial. The default mode should however still strive to allow the user to enter expressions as they appear in ordinary texts (it is still far from perfect in this respect), without the need to read a manual..
