Let's go one step at a time.

We start with the results array, which is empty: 

var results: [Int] = []

You then created the loop, using multiplier as the loop variable:

var results: [Int] = []
for multiplier in 1...10 { 

}

Now, we want to append something into the results array. We use dot notation to add items into an array. Something like:

var results: [Int] = []
for multiplier in 1...10 { 
  results.append()
}

What we want to append into the array is the value of multiplier multiplied by 6. That gives us:

var results: [Int] = []
for multiplier in 1...10 { 
  results.append(multiplier * 6)
}

I hope that explains it fully for you.

Steve.

Hi there,

You don't need to put a string together. The question says Once you have a value, append it to the results array.

You want to use the loop variable, multiplier, and multiply it by 6. Use the append() method on the results array (use dot notation) to add multiplier * 6 to the array.

I hope that makes sense.

Steve.
