# given the isDivisible function, create another function called is not divisible which also takes in two parameters, name

namely the dividend and the divisor. it should also return a bool. the goal of this function is to let you know whether a dividend is NOT divisible by the divisor( the function can return only a bool not an optional

divisible.swift
```func isDivisible(#dividend: Int, #divisor: Int) -> Bool {
if dividend % divisor == 0 {
return true
} else {
return false
}
}

func isNotDivisible(#dividend: Int, #divisor: Int) -> Bool {
return dividend % divisor != 0 {
}
isNotDivisible(4, divisor: 2) // false
isNotDivisible(5, divisor: 2) // true
```

Just a few minor adjustments, you have the bulk of it correct.

The return on the isNotDivisible has an open bracket '{' which needs to be removed and the test cases below are missing the 'dividend' parameters.

```func isDivisible(#dividend: Int, #divisor: Int) -> Bool {
if dividend % divisor == 0 {
return true
} else {
return false
}
}

func isNotDivisible(#dividend: Int, #divisor: Int) -> Bool {
return dividend % divisor != 0
}
isNotDivisible(dividend: 4, divisor: 2) // false
isNotDivisible(dividend: 5, divisor: 2) // true
```
