Hey Kevin,

You're on the right track, you just have the ++ on the wrong side. Both will do the same essentially, but its the way the question is worded that makes one right and one wrong. Also, there is not supposed to be a space between the value and the operators. So, for this task, you need, 

let totalScore =  ++initialScore

As per the Apple Documentation:

  • if the operator is written before the variable, it increments the variable before returning its value.
  • If the operator is written after the variable, it increments the variable after returning its value.

Keep Coding! :)
