Confused because --- when adding a WHERE clause, don't you need to make that WHERE clause = to a column name? In this case, wouldn't it be "= (1,4)"?

It would be = if you were checking a specific column number as in WHERE id = 1 but here we're checking against a set of values. There's another keyword that you're supposed to use here.
As a hint, they're asking for what would be the shorter way to do this: WHERE id = 1 OR id = 4

I realized the BETWEEN when I noticed before I even saw the second post. Much appreciated.

Courses Plus Student 94,610 PointsYou're welcome.
Are you sure that it passed with BETWEEN?
That wouldn't be correct. In my answer, I was trying to lead you to using IN

12,842 PointsI'm rusty on using IN because so far I've used AND & OR more...when would we want to use IN vs. OR?
Jason Anello
Courses Plus Student 94,610 PointsI'd say use IN whenever you can because it's less typing and less chance of making an error.
In this example you have WHERE id = 1 OR id = 4 vs. WHERE id IN (1, 4)
The IN version is more concise and you only have to type the column name one time.

Courses Plus Student 94,610 PointsI realized you might be having trouble with this because it's part of the prerequisite knowledge for this course.
Here's the video from "SQL Basics" that should help you with what you need for this question.

I would recommend you take that entire course if you haven't already. There's also a cheat sheet you can download in the teacher's notes which might help you get through this course easier.
