Explanation
When 9 is multiplied by any number, the sum of the digits in the product is always 9.
Examples:
- 9 × 1 = 9 (sum of digits: 9)
- 9 × 2 = 18 (sum of digits: 1+8 = 9)
- 9 × 3 = 27 (sum of digits: 2+7 = 9)
- 9 × 4 = 36 (sum of digits: 3+6 = 9)
And so on. This property holds true for all multiples of 9.
