문제풀이

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

        int A = scan.nextInt();
        int B = scan.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);
    }
}

• 백준 1000문제와 같이 풀어주면 됨
• 사칙연산 문제이기 때문에 간단한 문제

주의사항

• 공백 단위로 입력해야함
