I do not know what I am doing wrong here, even testing it in Xcode.

let value = 200 let divisor = 5

let someOperation = 20 + 400 % 10 / 2 - 15 let anotherOperation = 52 * 27 % 200 / 2 + 5

// Task 1 - Enter your code below var result = value%divisor result == 0 let isPerfectMultiple = result isPerfectMultiple == result

operators.swift
```// Enter your code below
let value = 200
let divisor = 5

let someOperation = 20 + 400 % 10 / 2 - 15
let anotherOperation = 52 * 27 % 200 / 2 + 5

var result = value%divisor
result == 0
let isPerfectMultiple = result
isPerfectMultiple == result
```

For starters, "result" is supposed to be a constant, not a variable. Then to check whether 200 / 5 results in a perfect multiple (0), we first create the result constant and assign it to the remainder of 200 / 5 (which is 0), using the remainder operator. Finding the boolean (true or false) value of whether or not the value of "result" (200 / 5) is 0 can be done in one line let isPerfectMultiple = result == 0

```// Enter your code below
let value = 200
let divisor = 5

let someOperation = 20 + 400 % 10 / 2 - 15
let anotherOperation = 52 * 27 % 200 / 2 + 5
