there are several ways one way is {x | x > -2}
this is read as the set of all numbers, x, such that x is greater than -2.

In the cell where you want the mean to appear, write =AVERAGE(description of the cells containing the group of numbers) Or, when you have typed '=AVERAGE(', highlight the cells that you want to be in the set. This is easier instead of typing it in. Remember to close parentheses!
well you don't you have to mullet
another way to write 2542 is word form....
There are two ways of describing, or specifying the members of, a set. One way is by intensional definition, using a rule or semantic description. See this example: A is the set whose members are the first four positive integers. B is the set of colors of the French flag. The second way is by extension, that is, listing each member of the set. An extensional definition is notated by enclosing the list of members in braces: C = {4, 2, 1, 3} D = {blue, white, red}
A Venn diagram is a way to illustrate sets and their relation to each other. It would be much easier to explain with paper and pencil, but here goes: Suppose you have two sets, A = {2.4.6.8.10,12}, and B = {3,6,9,12}. Draw two ovals which overlap. Outside the left one, write "A", and write "B" next to the other. In the overlapping area, write the numbers 6 and 12. In the rest of the A oval, write 2, 4, 8, and 10. In the rest of the B oval, write 3 and 9. Now the A oval contains all the number in the set A, and the B oval contains all the numbers in set B. The overlapping section contains the numbers in A⋂B, the left space is AnotB and the right space is BnotA. The entire area inside the two ovals is A⋃B.
