New Vocabulary 1. Solution: A number (or ordered pair of numbers, or set of numbers) that produces a true statement when substituted for the variable(s) in an equation or inequality. 2. Inequality: Any mathematical sentence that contains the symbols >, <, ≥, ≤, or ≠ to compare two quantities 3. Multiplication Property of Equality - If you multiply each side of an equation by the same nonzero number, the two sides remain equal. 4. Multiplication Property of Inequality- When you multiply each side of an inequality by a negative number, the inequality symbol must be reversed for the inequality to remain true. 5. Division Property of Equality - If you divide each side of an equation by the same nonzero number, the two sides remain equal. 6. Division Property of Inequality- When you divide each side of an inequality by a negative number, the inequality symbol must be reversed for the inequality to remain true.
