Example: Demonstrating the Addition and Subtraction Properties of Inequality

Consider the true mathematical statement 4<2-4 < 2. If we subtract 55 from both sides, we get 45<25-4 - 5 < 2 - 5, which simplifies to 9<3-9 < -3. This remains a true statement. Alternatively, if we start with 4<2-4 < 2 and add 77 to both sides, we get 4+7<2+7-4 + 7 < 2 + 7, which simplifies to 3<93 < 9, another true statement. These numerical examples verify the Addition and Subtraction Properties of Inequality, demonstrating that adding or subtracting the same quantity from both sides of a true inequality always results in another true mathematical statement with the sign pointing in the exact same direction.
