495 PointsGreat job with the first task! In this task, we have two math operations. Without computing the values of those
I'm unclear on what I'm doing wrong. I don't recall being instructed on how to do this and at $600 a month this is becoming an expensive guessing game.
// 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
let isPerfectMultiple = result == 0
let isGreater = someOperation >= anotherOperation == 1

7,786 PointsI've not done swift before but usually when thinking of logic that needs to meet more than one requirement i think of && and ||.
so the question was: we'd like to know if the first operation, someOperation is greater than, equal to or less than anotherOperation.
When it says is greater than or equal to i know it would be >= as a symbol but then it says or less than aswell theres no symbol for greater then equal and less than. So first thing is i can do >= and check that and i can also do a seperate check <= which just makes me think of do check1 >= && do check2 <=.

495 PointsThanks very much Mr. Rahman.
May I say to the Treehouse folks... coming from someone with no iOS programming experience and only a couple months on the front end, this exercise is in no way an intuitive linear thought process. I have experience with && || and there was really very little indication that this exercise involved those operators. Given that this is my first few challenges in Swift, I think there could be some better explanation here.

495 PointsThat makes sense. Thank you for the clarification.

7,786 PointsNo worries :) I guess they could have mentioned it in a hint somewhere a lot more in your face if its basics.
But the hint did say use the >= kind of operators, i think using that hint you should have kind of seen you would need a >= and a <= which would lead you to a && || situation.

495 PointsI have tried assigning to a boolean value and that doesn't work.
