### Multiplying a repeating 6's number by 444

1. Choose a repeating 6's number (666, etc.)
2. Multiply it by 444
3. The product is:
- the first three digits are 295
- the next digits are 9's (three fewer than repeating 6's in the original number)
- the last three digits are 704

#### Example:

1. If the first number is 66666:
2. Multiply by 444. The product is:
- the first three digits are 295: 295
- the next digits are 9's (three fewer than repeating 6's in the original number): 99
- the last three digits are 704
3. So 66666 × 444 = 29599704.

See the pattern?

1. If the first number is 6666666:
2. Multiply by 444. The product is:
- the first three digits are 295: 295
- the next digits are 9's (three fewer than repeating 6's in the original number): 9999
- the last three digits are 704
3. So 6666666 × 444 = 2959999704.
Use the three rules and you will be giving these big products with ease.
