I am a graduate of Economic Sciences at the UBA (University of Buenos Aires, Argentina) and a Professor of Mathematics (CAECE University, Argentina) with 15 continuous years of university teaching of mathematics and statistics at UBA, University of Salvador and University of Business and Social Sciences (Argentina). I see mathematics from a different perspective. No recitation from memory. Each topic needs to be approached from its purest logic to understand and learn it and then think about it and explain it without having to resort to memory. I teach online classes from Buenos Aires, Argentina, of any mathematical/statistical subject at university level and above. I am the author of the Statistics subject program validated by the Universität Passau (Germany) so that its students can take that subject at the University of Salvador (Argentina).
