Subtraction Property: If you subtract the same value from both sides of an equation or inequality, the equality or inequality remains true.
Multiplication Property: If you multiply both sides of an equation or inequality by the same non-zero value, the equality or inequality remains true.
Division Property: \text{If you divide both sides of an equation or inequality by a non-zero value, the equality or inequality remains true.}
