Iteration

Pronunciation: /ˌɪ.tərˈeɪ.ʃən/ Explain

An iteration is a step in a repeating algorithm. For example, to find the square root of 37, one can note that 37 is close to 36, so the square root of 37 is close to 6, the square root of 36.

Iteration	Calculations
1	37 ÷ 6 ≈ 6.16667; (6 + 6.16667) / 2 = 6.08333
2	37 ÷ 6.08333 ≈ 6.08219; (6.08333 + 6.08219) / 2 = 6.08276
3	37 ÷ 6.08276 ≈ 6.08277
Table 1: Iterations

The actual value of the square root of 37 is about 6.08276.
