Mathematical methodologies are used in management science, and it is necessary to take calculate results. Indeed, the calculations are numerical materials based on mathematical modeling for business phenomena.
Nowadays, computational tools are useful for the business computations, and we know keen software tools for numerical computational methods. The principle skills to use the software are programming abilities.
For example, Excel VBA makes the effectiveness for computational decision-making, and MATLAB, Scilab, R and so on are expected to take solutions in business issues.
