An alternate method of taking square roots. The previous method is best, but this method is very good too, and maybe a little simpler.
For any estimate (or guess) we can improve the estimate by:
1. Dividing the estimate into the number we want the root of.
2. Add the quotient you get to the estimate.
3. Divide by two (average the quotient and estimate)
Each time you repeat this, you will improve the accuracy. Again, the previous method is better, perfect, but this method is very good as well, and we will need this strategy in the future.
