addition to being reasonably formal and unambiguous, your mathematical writing should be as clear and understandable to your intended readership as possible. Here are the rational numbers: Q = na b: a ∈ Z,b ∈ Z,b 6= 0 o. Instead of a ∈ Z,b ∈ Z, you can write a,b ∈ Z, which is more concise and generally more readable.
