A)

 - [1] Scanner

import java.util.Scanner;

public class Main {
 
	public static void main(String args[]) {
	
		//스캐너 선언
		Scanner sc = new Scanner(System.in);
		
		//nextInt() 활용 
		//정수형 변수에 저장
		int A = sc.nextInt();
		int B = sc.nextInt();
		int C = sc.nextInt();
		
		//출력
		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);	
		
		//스캐너 종료
		sc.close();
	}
	
}

 

 - [2] BufferedReader

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.StringTokenizer;

public class Main {
 
	public static void main(String args[]) throws IOException {
	
		//bufferedReader 선언
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		
		//readLine()으로 행 읽어오기
		String str = br.readLine();
		
		//StringTokenizer로 문자열 토큰 단위로 구분
		StringTokenizer st = new StringTokenizer(str, " ");
		
		//nextToken() 활용 토큰 값 가져오기
		//parseInt() 활용 정수형으로 변환 후 저장
		int A = Integer.parseInt(st.nextToken());
		int B = Integer.parseInt(st.nextToken());
		int C = Integer.parseInt(st.nextToken());
		
		//출력
		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);	
		
	}
