Beginner C# expected class, delegates, etc. errors math quiz

Which version of Visual Studio are you using? I downloaded your stuff from your Skydrive and it won't load in mine ... but I'm still using VS 2010 ... I suspect you've written this with VS 2012?

However, no matter ... I created a new solution and used your same Form. Your problem is that you have a lot of mis-matched curly-brackets. Fix all of those ... make sure for every { you have a }. A good way to always make sure you do that is when you write a method or an if ... always put both brackets in first, then fill in the code in-between. That way you'll be sure not to forget a bracket after the fact.

Also, you have a method name and put a ; after it. This isn't correct. You had this:

public void StartTheQuiz();
{
            // Fill in the multiplication problem.
            multiplicand = randomizer.Next(2, 12);
            multiplier = randomizer.Next(2, 12);
            timesLeftLabel.Text = multiplicand.ToString();
            timesRightLabel.Text = multiplier.ToString();
            product1.Value = 0;

            // Start the timer.
            timeLeft = 30;
            timeLabel.Text = "30 seconds";
            timer1.Start();
}

Note the ; on the first line. I'm sure that was just a typo, but you've got to learn to spot those. It should be this:

public void StartTheQuiz()
{
            // Fill in the multiplication problem.
            multiplicand = randomizer.Next(2, 12);
            multiplier = randomizer.Next(2, 12);
            timesLeftLabel.Text = multiplicand.ToString();
            timesRightLabel.Text = multiplier.ToString();
            product1.Value = 0;

            // Start the timer.
            timeLeft = 30;
            timeLabel.Text = "30 seconds";
            timer1.Start();
}
