import java.util.*;
// 注意类名必须为 Main, 不要有任何 package xxx 信息
public class Main {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int num = scanner.nextInt();
int sum = (int)Math.pow(num, 3);
// System.out.println(pow);
int a = num * num + 1 - num;
StringBuilder builder = new StringBuilder();
for (int i = 0; i < num; i++) {
builder.append(a);
builder.append("+");
a += 2;
}
builder.deleteCharAt(builder.length() - 1);
System.out.println(builder);
}
}
