## Inequalities - I

Summary
The content provides an in-depth exploration of inequalities, focusing on understanding and manipulating inequality symbols, the importance of considering all possible numbers, and specific operations that can be performed on inequalities.
• Inequalities are essential in mathematics for determining the relative sizes of values, using five key symbols to express these relationships.
• A common misconception is equating specific inequalities with similar, yet distinct, numerical ranges, highlighting the importance of recognizing all possible numbers, including positive, negative, integers, fractions, and decimals.
• Addition and subtraction operations can be performed on both sides of an inequality without altering the inequality's direction, similar to equations.
• Multiplication and division by positive numbers preserve the inequality's direction, while performing these operations with negative numbers reverses the direction.
• Practical examples and practice problems illustrate how to solve inequalities, including the application of these operations and the interpretation of solutions on a number line.
