My answers were also a mix of strings and numbers. I used the == comparison instead of === because it doesn't compare type. Here's my solution.

<p> <code> var quiz = [['What color do yellow and blue make?', 'green'], ['How many months are in a year?', 12], ['How many states are in the United States?', 50]]; var answer; var correct = 0;

function print(message) {
  document.write(message);
}

for (var i=0; i<quiz.length; i+=1) {
  answer = prompt(quiz[i][0]).toLowerCase();
  if (answer == quiz[i][1]) {
    correct += 1;
  }
}

print('You got ' + correct + ' questions correct!');
