Number Line

A number line is a visual representation of numbers in order, typically with zero in the middle and positive numbers to the right and negative numbers to the left. It is a useful tool for understanding the relative magnitude and position of numbers.

Parts of a Number Line

• Zero: The point at the center of the number line, representing the number 0.
• Positive Numbers: The numbers to the right of zero, increasing in value as you move to the right.
• Negative Numbers: The numbers to the left of zero, decreasing in value as you move to the left.
• Integers: The set of whole numbers (both positive and negative) and zero, which are evenly spaced along the number line.

Using a Number Line

Number lines can be used for various mathematical operations, such as addition, subtraction, multiplication, and division. They can also help with understanding concepts like absolute value and comparing the magnitude of numbers.
