The bid-rent curve has a negative slope because the activities balance the bid-rent with the cost of transportation to the point of attraction. Farther distances require greater transportation cost and thus reduce the amount of rent that can be paid. The bid-rent curve indicates why rents, and by inference land values, tend to be higher near central locations. Â« Better Business Bureau | big business Â».

Recursion in computer programming is exemplified when a function is defined in terms of simpler, often smaller versions of itself. The solution to the problem is then devised by combining the solutions obtained from the simpler versions of the problem.
Iteration is the act of repeating a process with the aim of approaching a desired goal, target or result. Each repetition of the process is also called an iteration, and the results of one iteration are used as the starting point for the next iteration.The pentagon on the right also is a good example of how iteration relates to recursion.Although iteration is used, for example, to parse a linked list, recursion is required when we step up to binary trees.
