    public static void main(String[] args) {
        System.out.println("\\    /\\");
        System.out.println(" )  ( ')");

        System.out.println("( 0 )\"\"\"\\");
        System.out.println("|\"^\"`    |");
        System.out.println("||_/=\\\\__|");
    }
}

1000번 A+B

    }
}

1001번 A-B

import java.util.Scanner;

public class Main {

        int b = sc.nextInt();
        System.out.println(a - b);
    }
}

10998번: AxB

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);

        int A = sc.nextInt();
        int B = sc.nextInt();

        System.out.println(A * B);
    }
}

1008번: A/B

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);

        int A = sc.nextInt();
        int B = sc.nextInt();

        System.out.println((double)A / B);
    }
}

10869번 사칙연산

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int a = sc.nextInt();
        int b = sc.nextInt();
        System.out.println(a + b);
        System.out.println(a - b);
        System.out.println(a * b);
        System.out.println(a / b);
        System.out.println(a % b);
    }
}

10926번 ??!

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.println(sc.next() + "??!");
    }
}

18108번 1998년생인 내가 태국에서는 2541년생?!

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.println(sc.nextInt() - 543);
    }
}

10430번 나머지 (오답?)

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int A = sc.nextInt();
        int B = sc.nextInt();
        int C = sc.nextInt();

        System.out.println((A+B) % C);
        System.out.println((A%C + B%C)%C);
        System.out.println((A*B) % C);
        System.out.println((A%C * B%C)%C);
    }
}

2588번 곱셈

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);

        int A = sc.nextInt();
        int B = sc.nextInt();

        sc.close();

        System.out.println(A*(B%10));
        System.out.println(A*(B%100/10));
        System.out.println(A*(B/100));
        System.out.println(A*B);
    }
}
