Multiplication of 4-Digit and 2-Digit Numbers
- The result of multiplying a 4-digit number by a 2-digit number can vary in terms of the number of digits in the product.
- The minimum number of digits in the product is 5 digits (e.g., 1000 × 10 = 10,000).
- The maximum number of digits in the product is 6 digits (e.g., 9999 × 99 = 989,901).
- If the product has 7 digits, the 4-digit number should be between 1000 and 9999, and the 2-digit number should be at least 70 (e.g., 1000 × 70 = 70,000 or 9999 × 71 = 70,989).
