#include <iostream>
using namespace std;

int main() {
    string s1, s2;
    while (cin >> s1 >> s2) {
        for (auto it = s1.begin(); it != s1.end();) {
            if (*it == ',')it = s1.erase(it);
            else it++;
        }
        for (auto it = s2.begin(); it != s2.end();) {

            else it++;
        }
        cout << stoll(s1) + stoll(s2) << endl;
    }

}
