SimplexCalc is a multivariable desktop calculator for Windows. It is small and simple to use but with much power and versatility underneath. It can be used as an enhanced elementary, scientific, financial or expression calculator.
In addition to arithmetic operation, more than hundred built-in constants and functions can also be used in your expression.
SimplexCalc also has the unlimited ability to extend itself by using custom (user-defined) variables. You can add your own variables for SimplexCalc in order to tackle complex problems with ease and fun. Even you can compile formula once and then calculate the result many times with different variable values.
With the brilliant designs and powerful features of SimplexCalc, you can bring spectacular results to your calculating routines.

DesktopCalc is an enhanced, easy-to-use and powerful scientific calculator with an expression editor, printing operation, result history list and integrated help. Desktop calculator gives students, teachers, scientists and engineers the power to find values for even the most complex equation set.
DesktopCalc uses Advanced DAL (Dynamic Algebraic Logic) mechanism to perform all its operation with the built-in 38-digit precision math emulator for high precision.
DesktopCalc combines fast "just-one-click" interface with broad set of functions. It was designed as a tool that is convenient for both elementary and scientific calculator.

DataFitting program performs statistical regression analysis to estimate the values of parameters for linear, multivariate, polynomial, exponential and nonlinear functions. The regression analysis determines the values of the parameters that cause the function to best fit the observed data that you provide. This process is also called curve fitting.
DataFitting gives engineers and researchers the power to find the ideal model for even the most complex data, by putting a large number of equations at their fingertips. DataFitting's built-in library includes a wide array of linear and nonlinear models from simple linear equations to high order polynomials.
