C# (In Console App) - Homework Help

The method DoMathProblem has 1 parameter: a MathDelegate type. What specifically can be passed to this method as an argument (see code below)?

For instance, if a method has an integer as its parameter, you can pass any expression that evaluates (or simplifies) to an integer number as an argument.

            Console.WriteLine($"The sum is {sum}");

int diff = genMath.subtract(o1);
            Console.WriteLine($"The difference is {diff}");

int mult = genMath.mul(o1);
            Console.WriteLine($"The product is {mult}");

Console.Write("Enter second operand: ");
int operand2 = convert.Int32(Console.ReadLine())

        }

// Sum of two numbers

        {

  Console.Write("Enter second operand: ");
int operand2 = convert.Int32(Console.ReadLine());
            return operand1 + operand2;
        }

// Difference of two Numbers   

static int subtract(int operand1)
        {

  Console.Write("Enter second operand: ");
int operand2 = convert.Int32(Console.ReadLine());
            return operand1 - operand2;
        }

// Multification of two Numbers

static int mul(int operand1)

        {

  Console.Write("Enter second operand: ");
int operand2 = convert.Int32(Console.ReadLine());
            return operand1 * operand2;
        }

  
    }
