#include <stdio.h>

int main() {
    // your code goes here
    int num1,num2,mul,i; //we are multiplying num1 with num2
    char multiSign;
    fflush(stdin);
    scanf("%d%c%d",&num1,&multiSign,&num2);
    int sum=0;
    while(num2!=0)
     {
         mul=num1*(num2%10);
         printf("%d\n",mul);
         sum=sum+mul;
         num2=num2/10;
     }
     i=sum;
     while(i!=0)
      {
         printf("-"); //this will print "-" for required number of times
         i=i/10;
      }
     printf("\n%d",sum);
    return 0;
