I have been struggling to get this formatted correctly. Any help would be appreciated. I put: (11 % 3 = 2); for my answer and it has a yellow caution triangle and says “Bad Assignment” pointing to the equals sign. ---

var remainder = 2 % 11; ---

The remainder operator % gives the remainder of the division of two numbers. **Example** **Usage** **Note** **Instructions** Set remainder equal to the remainder of 11 divided by 3 using the remainder (%) operator. 1. The variable remainder should be initialized `var remainder` 2)The value of remainder should be 2 `var remainder = 2;` 1. You should use the % operator var remainder = 2%11; ` ---

Can anyone clarify what they’re saying here? 17 % 2 = 1 (17 is Odd) 48 % 2 = 0 (48 is Even) “Set remainder equal to the remainder of 11 divided by 3 using the remainder (%) operator.” var remainder = 2%11; Where did 11 / 3 go? ---

> [@Forum](#): > > 2%11; The above was an example. It is pretty easy but everyone has to be verbose when explaining shit here. For 11 % 3 all you do is divide 11/3, which =3 with a remainder of 2. can double check by 3x3=9 11-9=2(same as the remainder) ---

I have no idea what the final part of this task was on about. I understand the following `17 % 2 = 1 (17 is Odd)` `48 % 2 = 0 (48 is Even)` In the final part, the correct answer is `var remainder = 2 % 11;`, but I have no idea what this has to do with `11 / 3`. ---

I entered “var remainder = 11 % 3;”, which the system accepted as correct. However, looking here I see var remainder = 2 % 11; is supposed to be the correct answer. Can anyone please clarify whether 11 % 3 really is the correct syntax, and if not, why not? TIA. ---

I think it’s this ``` var remainder = 11 % 3; ``` ---

Some info about the operator [https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Operators/Arithmetic\_Operators#Remainder\_()](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Operators/Arithmetic_Operators#Remainder_()) I think free code camp accepts the answer because the result of `2 % 11` is coincidentally the same `11 % 3`. I got a bit confused about what they wanted, because they were talking about finding whether a number was odd or even earlier on in the tutorial. ---
