Summary
Key learning points of this module:
- An inequality is a statement that one value is not equal to another value.
- A linear inequality in one variable is a statement that a first-degree expression is greater than (>), less than (<), greater than or equal to (≥), or less than or equal to (≤) a value.
- Linear inequalities are solved just like linear equations, but if both sides are multiplied or divided by a negative number, the inequality symbol is reversed.
- You can use the isolating variable method to solve absolute value equations.
- Similar to the absolute value of a number, the absolute value of an expression is also always positive.
- Absolute value can also be used in cases of inequality.
