Prime numbers have two factors. The sum of their proper divisors is always 1.
The smallest two-digit composite number is 10, which is the product of 2 and 5. The largest two-digit composite number is 99, which is the product of 3 and 33. To find the sum of the smallest and largest two-digit composite numbers, we add 10 and 99, resulting in 109.
