Chapter 3: Working with Negative
Numbers
Negative numbers are an essential aspect of algebra,
representing values less than zero. They play a critical role in
various mathematical operations and real-world contexts. This
chapter explores the concept of negative numbers, their
operations, and their practical applications.
The Number Line and Negative Numbers
The number line is a visual representation of numbers arranged
in order, with zero at the center, positive numbers to the right,
and negative numbers to the left. Negative numbers are
denoted by a minus sign (−) before the number, indicating their
position below zero. For example, −3 is three units to the left of
zero on the number line.
Understanding the number line and the placement of negative
numbers is crucial for grasping their behavior in mathematical
operations and real-world situations.
Addition, Subtraction, Multiplication, and
Division of Negatives
The operations of addition, subtraction, multiplication, and
division extend naturally to negative numbers, following specific
rules: -
