import java.io.*;

class Main {
  public static void main(String[] args) throws IOException {

    BufferedReader bf = new BufferedReader(new InputStreamReader(System.in));
    BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(System.out));

    int num = Integer.parseInt(bf.readLine());

    for ( int i = 0; i < num; i++ ) {
      String temp = bf.readLine();
      String[] arr = temp.split(" ");
      int a = Integer.parseInt(arr[0]);
      int b = Integer.parseInt(arr[1]);
      bw.write((a+b) + "\n");
    }
