Anna has written all the three-digit numbers on the blackboard, each appearing exactly once. Boglárka has erased Anna's numbers one by one, replacing them with the number obtained by subtracting the last digit from the sum of the first and the second digit. For example, 225 is replaced by $2+2-5=-1$ and 973 is replaced by $9+7-3=13$. Find the sum of numbers written on the blackboard by Boglárka.
