* BufferedWriter.flush는 맨 마지막에 한 번만 하면 된다.

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;

public class Main {

	public static void main(String[] args) {
		try {
			BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
			BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(System.out));

			int N = Integer.parseInt(br.readLine());
			for (int i = 0; i < N; i++) {
				String str = br.readLine();
				int num1 = Integer.parseInt(str.split(" ")[0]);
				int num2 = Integer.parseInt(str.split(" ")[1]);
				
				bw.write(num1 + num2 + "\n");
			}

			bw.flush();
			bw.close();
		} catch (IOException e) {
			// IOExeception
