Set Symbols. A set is a collection of things, usually numbers. We can list each element (or "member") of a set inside curly brackets like this: Common Symbols Used in Set Theory In other words, z-score is the number of standard deviations there are between a given value and the mean of the data set. If a z-score is zero, then the data point's score is identical to the mean. If a z-score is 1, then it represents a value that is one standard deviation from the mean. Z-score may be positive or negative. So, cardinal number of set A is 7. That is n (A) = 7. Example 2 : A = {x : x is a prime factor of 12} Solution : To find the cardinal number of the given set, we have to count the number of elements of the set. So, first we have to list out the elements of the set.Complex. Complex numbers, such as 2+3i, have the form z = x + i y , where x and y are real numbers. x is called the real part and y is called the imaginary part.
