I would like to be able to add, for example, a text box for someone to capture their weight, another box for their size to be captured and when a button is pressed, the result of their Body Mass Index appears in another non-editable text box. The above to create simulators for students in the Physical Education class at the Baccalaureate level. Other examples of calculations are: Basal Metabolism and physical activity to simulate the required Kilocalories according to weight, height, age, gender, etc.
