If this doesn t make sense then just come up with your own a b set and solve.
What does c mean in math sets.
I just made up the a b sets just now because i needed an somebody to do an example on them so i can use it to help me with my real a b set i m doing now if you understand what i mean.
Find a and b and explain what that number represents.
Symbols save time and space when writing.
That symbol as used in precalculus is one of the number set symbols math mathbb r math for the reals math mathbb n math for the naturals math mathbb.
So for example a is a set and a is an element in a.
Same with b and b and c and c.
Now you don t have to listen to the standard you can use something like m to represent a set without breaking any mathematical laws watch out you can get π years in math jail for dividing by 0 but this notation is pretty nice and easy to follow so why not.
Example a 4 5 12 13 13 20 b 3 4 12 14.
Common symbols used in set theory.
A mathematical concept is independent of the symbol chosen to represent it.
A set is a collection of things usually numbers.
