Stuck in challenge 1 of 1 in Swift Collections and Control Flow

I do not know what to do here. I think some of the problem is that English is not my first language. I do not know what "a multiple by 7" means. But can anyone point me in the right direction. Where should I start?

operators.swift 
var results: [Int] = []

for n in 1...100 {
    // Enter your code below

    // End code 
}

So a multiple is a number that when divided by a given number will not have a remainder. For example 14 is a multiple of 7 because 14 divided by 7 is 0. You use the % sign find the remainder of two numbers.

Below n % 2 will find if it is odd or even and n % 7 will find if it is a multiple of 7.

var results: [Int] = []

for n in 1...100 {
    // Enter your code below
    if n % 2 != 0 && n % 7 == 0 {
      results.append(n)
    }
    // End code 
}

Hi! I believe the task would be wanting you to multiply (times) a range of numbers by 7. For example, if the multiplier was 2, it would read: 2 * 7

Hopefully that helps point you in the right direction. If you need further help with this specific challenge, it would be great if you posted a direct link to it for us to be able to see the exact requirements.

Best luck! :)

Thank you both! There may be some problem with the language sometimes, but it helps to get it explained :)
