The problem is with this part of your code:

        if(num = -)
        {
            Console.Write("You must enter a positive number");
        }

You haven't given a valid condition inside the brackets so the compiler isn't expecting to see the brackets and is throwing an error.

To check to see if the number is negative then you would use the less than operator to check is num is less than 0. Like this:

        if(num < 0)
        {
            Console.Write("You must enter a positive number");
        }
