{2, -17/19, 5 2/3, -0.0036, 1.343434... (recurring), pi, sqrt(37), 0} is an example of a set of real numbers. I have not gone beyond that set since the question suggests that you are not yet at a level to grasp complex numbers or quaternions.
Add up the numbers, and then divide by the number of numbers in the set. This will give you the mean.

False. The collection of natural numbers is an example of a set, not an element. An element is an individual member of a set, while the collection of natural numbers is a set itself.
Even in math, the word "infinite" has different meanings in different contexts. Infinite sets include the set of natural numbers, the set of integers, the set of rational numbers, the set of irrational numbers, the set of real numbers, and the set of complex numbers.
The set of complex numbers is a field which contains the set of real numbers as a proper subfield.
For example the set of all numbers which are integer multiples of 4 is a subset of all the numbers exactly divisible by 2.
The set of Rational Numbers is a [proper] subset of Real Numbers.
There is only one null set. It is 'the' null set. It is a set which does not contain any numbers.
NO. The set of numbers in Set B and the set of numbers in Set C CAN be the same, but are not necessarily so.For example if Set A were "All Prime Numbers", Set B were "All Even Numbers", and Set C were "All numbers that end in '2'", A union B would equal A union C since 2 is the only even prime number and 2 is the only prime number that ends in 2. However, Sets B and C are not the same set since 4 exists in Set B but not Set C, for example.However, we note in this example and in any other possible example that where Set B and Set C are different, one will be a subset of the other. In the example, Set C is a subset of Set B since all numbers that end in 2 are even numbers.
In any given set, the mean is the average, which is the total of the numbers divided by how many numbers there are. Ex. (10, 17, 20, 45, 68) 68 + 45 + 20 + 17 + 10 = 160 There are 5 numbers in this set. 160/5 = 32 The mean is 32.
Just add all the numbers, then divide by the size of the set. For example, if you have a set of five numbers, add all of them, then divide the result by five.
