Hey there, I'm trying to figure out how to write the right condition to check if a number is both odd and a 7 multiple

Im using this condition in the Collections and Control Flow's task:

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

What's not working here? Thanks! Roy

logicalOperators.swift 
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 there! Oh wow you're close. In fact, if I change one single character it passes. And I'll give you a hint. I change an equal sign to an exclamation remark. Remember, if a number % 2 is equal to 0 it is even... not odd :smiley:

Give it another go with these hints in mind! :sparkles:

Ahhh! Can't believe I missed that, you're so right!

  • Changed the first equal sign to an exclamation remark as you suggested. #success Thank you Jennifer!

As it says use not operator i.e !(n%2 == 0) for n in 1...100 { // Enter your code below if !(n % 2 == 0) && (n % 7 == 0){ results.append(n) } else{ print("not even") }

}
