import java.util.Scanner;

public class Main{
    public static void main(String args[]){
        Scanner scan = new Scanner(System.in);
        while(scan.hasNext()){
            int n = scan.nextInt();
            int sum = 0;
            for(int i = 0; i < n; i ++){
                String s = scan.next();
                String[] sArray=s.split("[()]");
                int system = Integer.parseInt(sArray[1]);
                int x = Integer.parseInt(sArray[0], system);
                sum += x;
            }
            System.out.println(sum);
        }
    }
}
