# Another entirely wrong attempt

Very difficult to grasp. I have been doing the practice videos and trying to revise but I am struggling to understand! Does nayone have any advice or ideas on how I can get a better grasp of how to get through these challenges rather than asking for help on every one! :(

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

for n in 1...100 {
if !n%2 || n%7
n.append()

// End code
}
```

Hi there! I see that you've been working on this and I looked back at my comment to you on your previous post and one of the videos opens for me, but the other one doesn't and I have no idea why.

But I'd like to at least congratulate you on understanding that the modulus/modulo operator should be used here and the append method.

Here's how I did it (with comments):

```var results: [Int] = []

for n in 1...100 {
if n % 2 != 0 && n % 7 == 0 { //if the number is odd and evenly divisible by 7
results.append(n) //append the number to the results array
}
// End code
}
```

Ok so if a number is evenly divisible by another number, it will have a remainder of 0. Even numbers are all numbers that are evenly divisible by 2. So first I say if the number is not evenly divisible by two (ie it is odd) and the number is evenly divisible by 7, then take that number and append it to the `results` array.

This means that the resulting array will contain the numbers: 7, 21, 35, 49, 63, 77, 91.

Hope this clarifies things!

As for finding other answers, you can always search the forums. Take a look at this link which contains no less than 3 pages of students who have previously had this question.

Thanks again for explaining, you are a great help! I'm going to recap some of my previous work and get back on the horse!
