The subject would be Xestión Financeira (Financial Management) in the 2nd year of the Higher Cycle of Administration and Finance. The topic would be loans and amortisation systems; for example, the French system or constant amortisation terms.
In an offline version, it would be a lesson in which I would use a sample exercise and solve it step by step with the help of the board and the provided instructions.
We would explain the characteristics of the method (then I would upload the presentation in the Moodle with all the basic concepts); we would build the amortisation table step by step (then I would upload the presentation, a model of the amortisation table with the basic formulas and the solved exercise in the Moodle).
