class test {
 public static void main (String [] args) throws IOException {
   // Use BufferedReader rather than RandomAccessFile; it's much faster
   BufferedReader f = new BufferedReader(new FileReader("test.in")); // input file name goes above
   PrintWriter out = new PrintWriter(new BufferedWriter(new FileWriter("test.out")));
   // Use StringTokenizer vs. readLine/split -- lots faster
   StringTokenizer st = new StringTokenizer(f.readLine()); // Get line, break into tokens
   int i1 = Integer.parseInt(st.nextToken());    // first integer
   int i2 = Integer.parseInt(st.nextToken());    // second integer
   out.println(i1+i2);                           // output result
   out.close();                                  // close the output file
 }
