Perhaps you mean Mathcad and MATLAB. Mathcad has a convenient GUI for writing equations and solving them symbolically or numerically. MATLAB has a relatively easy-to-learn programming language and a *huge* collection of built-in functions and tools for numerical math calculations. Go to their web sites and read more about them, and maybe request trial versions: https://www.mathcad.com/ https://www.mathworks.com/products/matlab/
