Question

The text begins by asserting that 'All of mathematics can be described with sets.' What do you think about this assertion, based on the math you've learned before? Give an example of a mathematical object that is not obviously a set. (Alternatively, if it is obvious to you how all mathematical objects can be described with sets, then please write a short explanation why.)​

Answer 1

Answer:

Example: Set A = {1,2,3,4} and set B = {5,6,7,8} are disjoint sets, because there is no common element between them.

Step-by-step explanation:

Set theory has its own notations and symbols that can seem unusual for many.

...

For two sets A and B,

n(AᴜB) is the number of elements present in either of the sets A or B.

n(A∩B) is the number of elements present in both the sets A and B.

n(AᴜB) = n(A) + (n(B) – n(A∩B)
