Mathematically speaking, Calculus is the study of change. It comes from the Latin word calculus, meaning small pebble. It comprises several related subfields of real analysis:

Note that the fundamental concepts of functions, graphs, and limits, which are studied at the beginning of courses in differential calculus, are often first introduced in earlier classes (most notably intermediate algebra and precalculus). Sequences are also typically first studied in earlier classes.
