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

public class Main extends Exception {
    public static void main(String[] args) throws IOException {

        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        StringBuilder sb = new StringBuilder();
        StringTokenizer st = new StringTokenizer(br.readLine());

        int bankA = Integer.parseInt(st.nextToken());
        int bankB = Integer.parseInt(st.nextToken());

        st = new StringTokenizer(br.readLine());
        int chichken = Integer.parseInt(st.nextToken());
        int answer = 0;

        if ((bankA + bankB) >= chichken * 2){
            answer = (bankA + bankB) - (chichken * 2);
        }else{
            answer = bankA + bankB;
        }

        sb.append(answer);
        System.out.println(sb.toString());

    }
}
