i don't know the answer to this questions. cannot understand what question asks

var results: [Int] = [1,2,3,4,5]

for multiplier in 1...10 { print("the multiple is (multiplier) times 6, which is equal to (multiplier*6)") results.append(multiplier*6) }

loops.swift 
// Enter your code below
var results: [Int] = [1,2,3,4,5,6,7,8,9,10]

for multiplier in 1...10 { 
print("the multiple is \(multiplier) times 6, which is equal to \(multiplier*6)")
results.append(multiplier*6)
}

MINJI, they want an array filled with the results of 6 times each of the numbers in the range 1 through 10 inclusive. 

var results: [Int] = []

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

You need a loop counter. Here I name it i. i will be 1 the first time through the loop, 2 the next time, etc.

Then you need a constant, multiplier, to store the results of each multiplication.

Then you need to add (append) the results of the calculation (which is in multiplier) to the results array.

Hope this helps.
