⩥ element (∈). Answer: a member of a set.
⩥ natural numbers (N). Answer: the set {0, 1, 2, 3, ...}.
⩥ rational numbers (Q). Answer: numbers that can be expressed as the
quotient of two integers.
⩥ real numbers (R). Answer: all the numbers on the number line,
including both rational and irrational numbers.
⩥ integers (Z). Answer: the set of whole numbers, including negative
numbers, zero, and positive numbers.
⩥ set-builder notation. Answer: a notation used to describe a set by
stating the properties that its members must satisfy.
,⩥ A equals B (=). Answer: a statement indicating that two sets or
quantities are identical.
⩥ A is a (proper) subset of B (⊂). Answer: a set A is a proper subset of
set B if all elements of A are in B and A is not equal to B.
⩥ A is a superset of B (⊇). Answer: a set A is a superset of set B if it
contains all elements of B.
⩥ the union of A and B (∪). Answer: the set containing all elements that
are in A, in B, or in both.
⩥ the intersection of A and B (∩). Answer: the set containing all
elements that are both in A and in B.
⩥ Cartesian product of A and B (×). Answer: the set of all ordered pairs
(a, b) where a is in A and b is in B.
⩥ domain of the variable. Answer: the set of all possible input values for
a function.
⩥ abstract objects. Answer: concepts or entities that do not have a
physical existence but are used in mathematical reasoning.
,⩥ culturally literate. Answer: having knowledge and understanding of
various cultural contexts and practices.
⩥ mathematician. Answer: a person who specializes in the field of
mathematics.
⩥ mathematical theory. Answer: a system of ideas and principles that
explain mathematical concepts and relationships.
⩥ written explanations. Answer: descriptions or clarifications of
mathematical concepts expressed in complete sentences.
⩥ defined terms. Answer: specific words or phrases that have been given
precise meanings within a mathematical context.
⩥ incomplete grasp of definitions. Answer: a lack of full understanding
of the meanings of terms, which can hinder comprehension.
⩥ set. Answer: a collection of distinct objects considered as a whole.
⩥ N+. Answer: the set {1, 2, 3, ...}, representing natural numbers
excluding zero.
, ⩥ Element. Answer: When x is a member of set X, we say that x is an
element of X, denoted as x ∈ X.
⩥ Not an Element. Answer: When x is not a member of set X, we write
x /∈ X.
⩥ Natural Numbers. Answer: The set of positive integers, denoted by N.
⩥ Set Membership Notation. Answer: A shorthand notation to express
membership in a set, e.g., '4 ∈ N' means '4 is in the set of natural
numbers'.
⩥ Multiple Elements Notation. Answer: To express that multiple
elements are members of the same set, we can write '2, 4 ∈ N' to mean '2
∈ N and 4 ∈ N'.
⩥ Explicit Set Definition. Answer: A set can be defined by listing its
elements explicitly, e.g., {1, 3, 5, 7} is the set of the first four odd
numbers.
⩥ Set Order Irrelevance. Answer: The order of elements in a set does not
matter; {1, 3, 5, 7} is the same as {1, 5, 3, 7}.
