The term 'greatest lower bound' of a subset A of real number R is also called .............  (NB: Answer should be lower case)

Which of the following is the name for an algebraic statement that includes the greater-than or less-than symbols?conicequalityinequalitygreater than

The   is the difference between the largest and smallest values that occur in a set of data.

Suppose we have two sets A & B, then A < B is:True if len(A) is less than len(B).True if A is a proper subset of B.True if the elements in A when compared are less than the elements in B.True if A is a proper superset of B.

n this problem for b > a are both real numbers, (a, b] = {c ∈ R : b ≥c > a}. Determine the following subset of R : ∩i∈N (1 − in , 1 + in ]

Suppose that S and T are nonempty subsets of R which are bounded below, and thatS ⊆ T . Prove that inf S ≥ inf T .
