The two digits that have a sum of 8 and a product of 15 are 3 and 5. When you add them together, 3 + 5 equals 8, and when you multiply them, 3 × 5 equals 15.
49, 67, 85

The two digits that equal 150 are 1 and 5, when combined as the two-digit number 15 multiplied by 10. However, if you're looking for two separate digits that sum to 150, that is not possible since the maximum sum of two single digits (9 + 9) is 18. Therefore, there are no two digits that can equal 150 in a traditional sense.

Must end in 5 and be less than 2500, so only 1735 fits.
The sum of your digits is the total number arrived at after adding two or more numbers.
Eleven 1 + 1 = 2 1 x 1 = 1

The three-digit number you are describing is 730. It is a multiple of 10, greater than 600, and the sum of the first two digits (7 + 3) equals 10, while the difference (7 - 3) equals 4. However, the criteria provided do not seem to align correctly, as the difference cannot be 13 with the sum being 13. Please clarify the conditions for a correct answer.
