# I have no clue how to do this question

how do you input even of odds in code? or tell if you can divide by 7

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

for n in 1...100 {
if in !
// End code
}
```

You will want to use the modulo operator %. If a number is perfectly divisible by another a modulo operation returns zero. For example:

n % 7

equals zero if n is perfectly divisible by 7

n % 2

equals zero if n is perfectly divisible by 2 (and therefore even)

So for this challenge you will want to check if n % 7 == 0 and n % 2 != 0 to see if the number is both perfectly divisible by 7 and odd (not even).

You can use the AND operator (&&) to specify both conditions need to be true in order for the loop to run.

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

for n in 1...100 {

if n % 7 == 0 && n % 2 != 0 {

results.append(n)
}

}
```
