### Multiplying a repeating 2's number by 66

1. Choose a repeating 2's number (222, etc.)
2. Multiply it by 66
3. The product is:
- the first two digits are 14
- the next digits are repeating 6's (two fewer than repeating 2's in the original number)
- the last two digits are 52

#### Example:

1. If the first number is 222:
2. Multiply by 66.
3. The product is:
- the first two digits are 14.
- the next digits are repeating 6's (two fewer than repeating 2's in the original number): 6.
- the last two digits are 52.
4. So 222 × 66 = 14652.

See the pattern?

1. If the first number is 22222:
2. The product is:
- the first two digits are 14.
- the next digits are repeating 6's (two fewer than repeating 2's in the original number): 666.
- the last two digits are 52.
3. So 22222 × 66 = 1466652.
