When multiplying numbers, the number of digits in the product is determined by the sum of the number of digits in the multiplicands. In the case of 02 x 02, both multiplicands have one digit, so the product has two digits. Therefore, 02 x 02 equals 004. Similarly, in the case of 003 x 003, both multiplicands have two digits, so the product has four digits. Therefore, 003 x 003 equals 0009. The leading zeros are used to maintain the correct number of digits in the product. **

Additionally, I suggest she continues to challenge herself creatively by experimenting with new storytelling techniques while staying true to her signature style that has made her a beloved author for generations. **
