Determine the number which when
multiplied by itself (squared) will
give you a product equal to the
first digit group under the radical
sign. If you cannot find a number
which when multiplied by itself
(squared) equals digit group under
the radical sign, select the number
which when squared is closest to
(and smaller than) the digit group.
Place the product of the number
multiplied by itself below the
group, subtract any difference, and
bring this difference down.
bring the next group down.
Double the trial square root (above
the radical sign) and place it to
