What does a fancy R mean in math?

set of real numbers
The set of real numbers is denoted using the symbol R or. and is sometimes called “the reals”. Real numbers can be thought of as points on an infinitely long line called the number line or real line, where the points corresponding to integers are equally spaced.

What are notations in geometry?

‘R’ is the set of real numbers. The equation has infinite number of solutions, meaning any real number is a solution: loading.

How do I find my Powerset?

The total number of subsets for a set of ‘n’ elements is given by 2n. Since the subsets of a set are the elements of a power set, the cardinality of a power set is given by |P(A)| = 2n. Here, n = the total number of elements in the given set. |P(A)| = 2n = 22 = 4.
