Squaring special numbers (5 and
                 repeating 3's)

1. Choose a number with a 5 and repeating 3's.
2. The square is made up of:
   • first digits: 28 & one fewer 4 than repeating 3's
   • next digits: 0 & one fewer 8 than repeating 3's
   • last digit: 9

   Example:

1. If the number to be squared is 5333:
2. The square has:

   first digits: 28 and one fewer
    4 than 3's                   2 8 4 4
next digits: 0 and one fewer
    8 than 3's                          0 8 8
last digit: 9                                 9

3. So 5333 x 5333 = 28,440,889.

   See the pattern?

1. If the number to be squared is 533333:
2. The square has:

   first digits: 28 and one fewer
   4 than 3's             2 8 4 4 4 4
next digits: 0 and one fewer
   8 than 3's                        0 8 8 8 8
last digit: 9                                  9

3. So 533333 x 533333 = 284,444,088,889.
