Abstract
The software Numericals is a tutorial for support to the learning of the techniques used for the Numerical Analysis mediates the programming of the main numerical methods, for the solution of engineering problems. The numerical methods are technical by means of which it is possible to formulate mathematical problems of such form which they can be solved using arithmetical operations. Although there are many types of numerical methods, share a common characteristic: invariantly a great number of tedious arithmetic calculations are due to make. With the development of efficient and fast digital computers, the paper of the numerical calculates in the solution of engineering problems has increased in considerable form in the last years. Besides to provide an increase in the power of calculation, the general availability of the computers and its association with the numerical methods it has influenced of very significant way in the process of the solution of engineering problems.
