Squaring special numbers (9 and
repeating 6's)
 Choose a number with a 9 and repeating 6's (use at least three 6's).
 The square is made up of:
 first digits: 93 & two fewer 4's than repeating 6's
 next digits: 31 & one fewer 5 than repeating 6's
 last digit: 6
Example:
 If the number to be squared is 9666:
 The square has:
first digits: 93 and two fewer
4's than 6's 9 3 4
next digits: 31 and one fewer
5 than 6's
3 1 5 5
last digit: 6
6
 So 9666 × 9666 = 93,431,556.
See the pattern?
 If the number to be squared is 966666:
 The square has:
first digits: 93 and two fewer
4's than 6's 9 3
4 4 4
next digits: 31 and one fewer
5 than 6's 3 1
5 5 5 5
last digit: 6
6
 So 966666 × 966666 = 934,443,155,556.
