Step 1: Using the remainder operator, compute the remai

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

let result = 200 % 2
let isPerfectMultiple = 0
result == isPerfectMultiple

``` Hi walter,

1) for task 1 you should use the variables value and divisor, not the values they are assigned to

```let result = value % divisor
```

2) for task 2 you need to assign the comparison between result and 0 (result == 0, which is true, because 200 divided by 5 has no remainder) to the constant isPerfectMultiple.

```let isPerfectMultiple = (result == 0)
```
