Integration
Integration is a simple way of "quickly" adding. In cases where you have a curve under a graph for example a velocity-time graph, the area under the curve will give you the distance. If you know the equation of the curve, integrating it will allow you to find the distance. Integration is also the opposite of differentiation.
