# 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 {

// 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 {
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 :)
