Mathematical modelling is mostly used to formulate and approximate a real world problem. Real world problems can be studied under strictly scientific laboratory environment or it can be studied in open natural areas like steep mountaineering paths or forests. Findings by a psychologist over human behaviors, sexual arrangements of fishes in seas or any numerical data on feeds of an elephant or any other daily life studies can be considered the base to modeling. These findings can always be converted to numeric values which is regarded as mathematical modeling of a real life problem.
