F ∪ H = {c, d, e, f, g, h}
F ∩ H = { }
Step-by-step explanation:

F ∪ H = {c, d, e, f, g, h}
The intersection is the list of only those elements that appear in both sets. (There are none.)
F ∩ H = { } . . . . the empty set

Answer:
It describes multiplication
Step-by-step explanation:
As you can see its 5x-5 (the x is say "by" or "of), So when you look at it you can clearly see it's multiplication.
