    This video explains what an integral is using Riemann Sum notation. It then goes on to explain why some integrals are positive and some are negative, and what an integral is actually finding. Some interesting examples are used in this video. The video also shows how you can find the integral of certain functions by looking at the graph and finding the area of the geometric shape. This is a pretty good lesson for learning and understanding what an integral is and how to compute it.
