What is "according to the number line?

According to the number line, numbers are ordered along a straight line. The number line is a visual representation of real numbers, where each point on the line corresponds to a unique number. Here are some key aspects:

• Origin: The point representing zero (0) is the origin or starting point of the number line.

• Positive Numbers: Numbers to the right of the origin are positive. As you move further right, the numbers increase in value. Understanding the concept of <a href="https://www.wikiwhat.page/kavramlar/Positive%20Numbers">positive numbers</a> is fundamental.

• Negative Numbers: Numbers to the left of the origin are negative. As you move further left, the numbers decrease in value. The idea of <a href="https://www.wikiwhat.page/kavramlar/Negative%20Numbers">negative numbers</a> is equally crucial.

• Ordering: Numbers increase from left to right. This means that any number on the right is greater than any number on the left. This leads to understanding of <a href="https://www.wikiwhat.page/kavramlar/Number%20Ordering">number ordering</a>.

• Integers: Whole numbers and their negatives, including zero, are called integers. On the number line, integers are evenly spaced points. More on <a href="https://www.wikiwhat.page/kavramlar/Integers">Integers</a>.

• Rational Numbers: Numbers that can be expressed as a fraction p/q, where p and q are integers and q is not zero, can also be represented on the number line. This involves understanding <a href="https://www.wikiwhat.page/kavramlar/Rational%20Numbers">rational numbers</a>.

• Irrational Numbers: Numbers that cannot be expressed as a simple fraction (e.g., √2, π) also have a place on the number line. They fill in the gaps between rational numbers. See also: <a href="https://www.wikiwhat.page/kavramlar/Irrational%20Numbers">irrational numbers</a>.

• Real Numbers: The set of all rational and irrational numbers is called the real numbers. The number line represents the entire set of <a href="https://www.wikiwhat.page/kavramlar/Real%20Numbers">real numbers</a>.

• Distance and Absolute Value: The distance of a number from the origin is its absolute value. The number line helps visualize the concept of <a href="https://www.wikiwhat.page/kavramlar/Absolute%20Value">absolute value</a>.

The number line is a foundational tool for understanding number relationships and performing basic mathematical operations.
