You must have accidentally added it while copying the question. The actual question was:
UPDATE games SET platform = "Cross-Platorm" WHERE id _____ (1,4);
So the question is looking for the operator which would check if id was either one of the two values in parentheses. Hint: it's a word, not a symbol.
Also, you should be aware that you cannot test for NULL using an equality ("="). To test for NULL you would use the identity operator ("IS").

18,036 PointsThe code is trying to say:
Update the games table, by setting the platform field to "Cross-Platform" (you are missing a "t" there) where the id IS either 1 or 4.
So they are looking for an id IN the set of (1, 4).

But since you only need to supply what goes in the blank, it doesn't affect the outcome.
