It is called creating or naming a set!
First of all, there are many different ways to express 3 in set builder notation, to be more precise, there are many different ways to express the set containing 3 as its only element. Here are a few ways {x∈R | x=3} or {x∈N | 2<x<4} or even just {3}
How many different ways can we arrange 9 objects taken 3 at a time?
1/4
12 There are 4 ways of choosing the first coin, leaving 3 coins from which to make the second choice. The number of combinations is therefore 4 x 3 = 12.
the ways in naming a set are: roster method, rule method and set builders
The 3 ways in naming an angle are..... 1.3points method 2.vertex method 3.Number method
the other one is intersection
=See the section in this article about that topic. http://en.wikipedia.org/wiki/Set_(mathematics)
One way is with curly brackets, for instance {3,4,5,6,7,8}. Another way to name this set would be {(x is a natural number)intersection(3<=x<=8)}
Degrees, radians, or polar coordinates. (3 ways)
Acute, obtuse, and right
Roster Method, for example {1, 2, 3, 4,5, 6} Set builder, for example {x:x is an element of Natural numbers, x

If you mean ways of naming angles then they are: acute, right, obtuse and reflex
naming the elements of a set. For example: {1, 2, 3, 4} or {-9} Remember: {your answer}
