Think of algebraic terms as areas of rectangles For example would be the area of a rectangle with length and breadth . When the rectangle is divided into two, along its length , such that one has the length while the other has the length then there are two rectangles. The areas of the rectangles and respectively. Hence the original area is equal to the sum of areas of the two rectangles .
