To find the smallest 4-digit number whose digits add up to 18, we need to consider the possible combinations of digits that add up to 18. The smallest 4-digit number starts with the digit 1, so we need to distribute the remaining 17 among the other three digits. The smallest combination is 1-6-6-5, which gives us the number 1566.
