public class Hello
{
    public static void Main()
    {
        // Your code here!
        
        int[] a = Console.ReadLine().Split(' ').Select(x => int.Parse(x)).ToArray();
        int sum = a[0] + a[1];
        int sub = a[0] - a[1];
        int mul = a[0] * a[1];
        int[] array = new int[]{sum,sub,mul};
        int max = array[0];
        foreach(var x in array)
        {
            if(x > max)
            {
                max = x;
