 Math Central Quandaries & Queries
 Question from Ron, a student: The question asked in a handout: 8k - 5 < 35, keI I believe the answer to k is 5. But what does the k e(E) I mean in this?

Hi Ron,

The letter $I$ stands for the set of integers and the statement $k \epsilon I$ means that $k$ is a member of the set $I$. In other words $k \epsilon I$ means that $k$ is an integer. $\epsilon$ is the Greek letter epsilon.
