Hi there! Up at the top they've set up an empty array for you. What they want is for you to use a for loop to start at 1 and go to 10. Every time through the loop you'll add (append) 6 times the number you're currently at. So at the end of your challenge if you were to check the values of the results array you'd have something that looks like this [6, 12, 18, 24, 30, 36, 42, 48, 54, 60]. Here's how we do this:

// Enter your code below
var results: [Int] = []

for multiplier in 1...10 {
    results.append(multiplier * 6);
}

Hope this helps!
