A Δ B = (A - B) U (B - A)

A^{C} = U - A

A ∩ B = A + B - A U B

J(A,B) = |A ∩ B|/|A U B|

J_{σ}(A,B) = 1 - J(A,B)

- cardinality
- a measure of the number of elements of the set
- coefficient
- a numerical or constant quantity placed before and multiplying the variable in an algebraic expression
- difference
- the result of one of the important mathematical operations, which is obtained by subtracting two numbers
- element
- an element (or member) of a set is any one of the distinct objects that belong to that set. In chemistry, any substance that cannot be decomposed into simpler substances by ordinary chemical processes.
