Iteration is the use of a repeated calculation involving a variable x where each answer is used as the value of x in the next round of calculations (iteration). The calculation to be done and staring value of x are carefully selected to ensure that repeated iterations generate an answer which becomes a more accurate solution for x with each iteration. More iterations are only required until an answer to the desired degree of accuracy is found.
