Default For Kids and Grownups -- Exploration3: the Incredible Shrinking Moon

Hey Gerald, do you know how to determine the accuracy of a
calculator? You give it the *27 squares test* Take the number 1.000
0001 and square it (multiply it by itself) 27 times.
The number you arrive at must be 674 530.4707.
The calculator in Windows will give you that plus many more
significant decimal places.
