With the time machine children learn a counting on times. The program presents therefore 10 different levels and three calculation methods. For solved exercises you can indicate music files as reward, which are played by the program. All calculations are recorded in a list for each pupil separately with all results across the last ten exercises. Thus the check of the learning progress and direct helping are facilitated for specific problems. More…

SuperPreciseMath contains a calculator for integer, rational, real and complex numbers with high precision (up to 10000 decimal digits). It can solve algebraic equations of up to 10 th degree and linear systems of equations. For the quick computation of prime numbers a prime number generator is available. Moreover prime factors and divisors can be calculated. More…

CurveFitter 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. More…

ScienCalc is a convenient and powerful scientific calculator. ScienCalc calculates mathematical expression. It supports the common arithmetic operations (+, -, *, /) and parentheses. The program contains high-performance arithmetic, trigonometric, hyperbolic and transcendental calculation routines. All the function routines therein map directly to Intel 80387 FPU floating-point machine instructions. More…
