Answer 2

\[\cup \]

umm is this a game?

Answer 4

No. These are literal algebra terms.

Answer 5

Union mean something that includes both of the stuff from any two sets!
For eg. = A = {1,2,3,4,5,6} , B = {1,2,3,7,8,9}
So A union B = {1,2,3,4,5,6,7,8,9}
But A intersection B = {1,2,3}

Answer 10

Now what does this mean?

Answer 11

I mean, what does it represent?

Answer 12

This represents an ordered pair which is a kind of relation between X and Y here! :D

Answer 13

\[\prime f\] And finally, what does this mean?

Answer 14

I don't quite see it but that f over there represents a function!
A function is just like a relation but
Unlike a relation every x value of a function MUST ALWAYS have an unique y value.
