Treehouse TeacherWell it's hard to know exactly which exercise/challenge/video you're referencing. But what they're asking is this: is the value stored in the variable i evenly divisible by 3.
Let's look at some examples.
4 divided by three results in 1 with a remainder of 1. That means 4 % 3 ==1.
5 divided by 3 results in 1 with a remainder of 2. So 5 % 3 == 2.
6 divided by 3 results in 2 with a remainder of 0. 6 % 3 == 0. Six is evenly divisible by three.
Hope this helps!
