Easy Squaring Shortcut 9 (Squaring numbers between 2000 and 2099)
1: Choose a number between 2000 and 2099. (Start with numbers below 2025 to begin with,
then graduate to larger numbers.)
2: The first two digits are: 4 0 _ _ _ _ _
3: The next two digits are 4 times the last two digits: 4 0 Y Y _ _ _
4: For the last three digits, square the last two digits in the number chosen (insert zeros when needed):

2. For the last three digits, square the last two:
25 × 25 = 625: _ _ _ _ 6 2 5
3. The middle two digits are 4 times the last two (keep the carry):
4 × 25 = 100 (keep carry of 1): _ _ 0 0 _ _ _
4. The first two digits are 40 + the carry:
40 + 1 = 41: 4 1 _ _ _ _ _
5. Then 2025 × 2025 = 4,100,625.
