Hi there! The challenge is simply testing your knowledge of the increment operators. Placement matters here as we want the total score and initial score to be the same. Take a look:

// Enter your code below

var initialScore = 8
let totalScore = ++initialScore

Note that if you put the increment operators on the other side of initialScore. Then totalScore would be equal to 8 and initialScore would be equal to 9. This is because the assignment would happen before the increment. Hope this helps!
