iOS Swift Basics Swift Operators Working With Operators: Part 2

Working with Operators

I'm not understanding this question. I looked at previous questions, and I still do not see what I am doing wrong. Can someone help guide me as to what I am doing wrong?

var initialScore = 7
let totalScore = initialScore + 1
let isWinner = totalScore != 10

Hi Lisa,

Your code is valid but the Treehouse code challenges have very specific requirements. For instance, the challenges will be very specific about any new variables or constants they want you to create.

In this case, they don't want you to create a new constant (what you have named totalScore). Instead, they want you to increment the initialScore with the unary plus operator (+=). It's confusing, I know, since they refer to the initialScore as "total score" in challenge description.

So if you write your code this way, it will pass:

var initialScore = 7
initialScore += 1
let isWinner = initialScore != 10

Ah! That makes sense. Thank you!
