iOS Development with Swift Techdegree Student 427 PointsI don't understand the second code challenge of the operators section.
// Enter your code below 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 let result = value % divisor
// Task 2 - Enter your code below result == 0 let isPerfectMultiple = true
someOperation >= anotherOperation thatResult = false let isGreater == thatResult
// Enter your code below
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
let result = value % divisor
// Task 2 - Enter your code below
result == 0
let isPerfectMultiple = true
someOperation >= anotherOperation
thatResult = false
let isGreater == thatResult

It's the correct value given the numbers that we have above, but what they want us to do is have the code produce the boolean value in a way that would still work with different numbers. That way we could build a block of code that's more generic, could be used with other numbers, run it through some logic, and maybe produce a result depending on what numbers are passed in.
let isPerfectMultiple = result == 0
let isGreater = someOperation >= anotherOperation
In this code, result == 0 might return true, or might return false. But we know it will assign a boolean value to isPerfectMultiple. Similarly, someOperation >= anotherOperation might return true or false and will assign the boolean value to isGreater.
