WebMar 5, 2009 · If A > 0 is a guess of the square root of the positive number Q, then a better approximation to √Q is given by. B = (A + Q/A)/2. Now you use B as an approximation and compute C = (B + Q/B)/2, and so on to get as close as you want to the value of √Q. We have shown elsewhere why the Babylonian Algorithm works.
