Problem for greenhorn

Friends,
I have just begun taking my first C++ class on-line and I am having problems with an if - else error. It is driving me crazy. I am attaching my program and hopefully one of you pros can help me out. I think I'm close. Thanks...

Code:

---

#include <iostream>
#include <cmath>
using namespace std;

int main()
{

        int num1, num2, answer;
        char operand;

        cout << "Please enter a number: ";
        cin >> num1;
        cout << "Now enter an operand: ";
        cin >> operand;
        cout << "Now enter a second number: ";
        cin >> num2;

        if (operand == '+')
                answer = num1 + num2;
                cout << "The answer is " << num1 << "+" << num2 << "=" << answer << endl;
        if (operand == '-')
                answer = num1 - num2;
                cout << "The answer is " << num1 << "-" << num2 << "=" << answer << endl;
        if (operand == '*')
                answer = num1 * num2;
                cout << "The answer is " << num1 << "*" << num2 << "=" << answer << endl;
        if (operand == '/')
                answer = num1 / num2;
                cout << "The answer is " << num1 << "/" << num2 << "=" << answer << endl;
        if (operand == '%')
                answer = num1 % num2;
                cout << "The answer is " << num1 << "%" << num2 << "=" << answer << endl;
        else 
                cout << "An invalid operator was entered" << endl;

        return 0;
}

You need curly braces. And remember that else only attaches to the one nearest if, so the invalid operator message will print every time that the operand isn't %.
