Why isn't this returning 2 correct answers?

Below is the beginning of my answer for the Conditional Challenge. Question one behaves as I expect, with Correct: 1 displaying in the browser if I answer it correctly.

However, when I answer the second question correctly, it still says "Correct: 1" in the browser. What's going on?

var correctAnswers = 0;
var question1 = prompt("What is 1 + 1?");
if (parseInt(question1) === 2) {
  correctAnswers =+ 1;
} else {
  correctAnswers;
}
document.write("<p>Correct: " + correctAnswers + "</p>");

var question2 = prompt("What is 2 + 2?");
if (parseInt(4) === 4) {
  correctAnswers =+ 1;
} else {
  correctAnswers;
}
document.write("<p>Correct: " + correctAnswers + "</p>");

Hi Margaret, just added some markdown to make your code easier to read.

Try swapping the increment-assignment operator from =+ to += and let me know if that works for you.

Cheers!

shouldn't the second question go like this? 

var question2 = prompt("What is 2 + 2?");
if (parseInt(question2) === 4)

Yep, that's a good catch. The challenge may just be expecting the if statement to evaluate to true. This is the benefit of having several people look at code - we may each find something different.
