Mathomatic is a portable, general-purpose computer algebra system (CAS) that can solve, differentiate, simplify, combine, and compare algebraic equations, perform standard, complex number, modular, and polynomial arithmetic, etc. It does some calculus and is very easy to compile/install, learn, and use. The symbolic math application with a simple command-line interface is designed to be a colorful algebra calculator that is reliable, responsive, and convenient to use. The symbolic math library is lightweight and easy to include in other software, due to being written entirely in C with no additional dependencies.

SPINA is software for determining constant structure-parameters of endocrine feedback control systems from hormone levels obtained in vivo. The first version of this cybernetic approach allows for evaluating the functional status of the thyroid gland, i.e. thyroid's secretory capacity (GT) and sum activity of peripheral deiodinases (GD).

ised is a command-line tool for generating number sequences and arithmetic evaluation. Unlike big GUI-based software (such as Mathematica, Derive, Matlab, or Octave), ised is intended for use in shell scripting, together with the GNU core utilities. Its main advantage is that all functions are generalized to operate on one-dimensional arrays. It can be used for loop indexing (much like seq), line-by-line arithmetic processing of files, floating point math for shells that don't support it natively, or interactive expression evaluation (i.e. as an extended calculator).

The qpfcalc application is a Qt frontend for pfcalc, a CLI pipe friction calculator. It is similar to gpfcalc, the GTK+ frontend for pfcalc. There are two versions of qpfcalc, one for Windows and one for Linux. The Linux version should be easy to compile and run on any Unix-like operating system with few minor modifications. For the application to function properly the pfcalc backend must be installed. For the Windows version, this is not needed as qpfcalc is distributed along with all the files needed to run, including pfcalc and Qt libraries.

Voynex calculator is a Web browser application designed to evaluate mathematical and JavaScript expressions. The main difference between it and other calculators is that it is possible to enter the whole expression at once instead of entering it step by step. For example, it can evaluate expressions like, "sin(sqrt(PI/3)+sqrt(PI/5))+cos(PI/2+1)", "x=pow(4,5)+3; 3*x+log(x)", or "0xff07+0x1c04*(0x45+0x55>>1)". The power of the JavaScript language itself is used to evaluate expressions of arbitrary complexity. It offers a wide set of mathematical functions to calculate trigonometrical, logarithmic, and other expressions.

Hormiga is a language designed to be simple and powerful, allowing users without software programming knowledge to make the programs needed to automate the calculations of everyday problems. Generally, it is necessary only for the users to be aware of the problem they want to solve. The language allows programmers to focus on the problem and not to worry about the interactive interface with the user. The programmer will have to state the instructions to solve a problem, in the same way they would do manually. The steps may depend one upon the other. Like most languages, Hormiga has support for functions and the possibility of creating libraries of commonly used code. Unlike most languages, Hormiga automatically and dynamically creates the graphical user interface (GUI) for programs, has support for calculating definite integrals in multiple dimensions, and incorporates a new concept called Step, similar to a procedure of Pascal, but allowing you to state dependences between them.
