please re-word the question, this makes no sense

I'm so confused by the question I don't even know how to ask a question about it

loops.swift
// Enter your code below
var results: [Int] = []
for multiplier in results {1...10
results = multiplier * 6             
}

Hello,

I'm assuming you passed the first part of the challenge.

Second Part

"Inside the body of the loop, we're going to use the multiplier to get the multiple of 6. For example, if the multiplier is 1, then the multiple is 1 times 6, which is equal to 6."

"Once you have a value, append it to the results array. This way once the for loop has iterated over the entire range, the array will contain the first 10 multiples of 6."

Let's break it down:

Inside the loop, we're going to use the multiplier to get the multiple of 6.

var results: [Int] = []

for multiplier in 1...10 {
  let result = multiplier * 6
}

Once you have a value, append it to the results array.

var results: [Int] = []

for multiplier in 1...10 {
  let result = multiplier * 6
  results.append(result)
}

What is happening is that the loop will iterate from 1 to 10 and we will use that to multiply it by 6. The result of that multiplication will be stored in the variable "result" and on the next line we will append it to the array named "Results".

Once the loop finishes, we will have an array full of those results.

I hope this clears It for you.

let me know if you have any more questions.

Good luck
