import java.io.*;
import java.util.StringTokenizer;

public class Main {
  public static void main(String[] args) throws IOException {
    BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

    int T = Integer.parseInt(br.readLine());

    BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(System.out));
    for(int i = 0; i <T; i++) {
      StringTokenizer st = new StringTokenizer(br.readLine());

      bw.write(Integer.parseInt(st.nextToken()) + Integer.parseInt(st.nextToken()) + "\n");
    }
      br.close();
      bw.flush();
      bw.close();

  }
