Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Set Notation
Set notation is a mathematical way to describe a collection of objects, known as elements. It often uses curly braces to enclose the elements or a rule to define the elements that belong to the set. For example, the notation {x | condition} indicates the set of all x that satisfy the given condition.
Natural numbers are the set of positive integers starting from 1 and extending indefinitely (1, 2, 3, ...). In some contexts, they may also include 0. Understanding natural numbers is crucial for identifying the elements of the set in the given question, as it specifies the type of numbers to consider.
Inequalities are mathematical expressions that describe the relative size or order of two values. In this case, the phrase 'not greater than 4' indicates an upper limit for the natural numbers in the set. This helps in determining which natural numbers are included in the set, specifically those that are 1, 2, 3, and 4.
