Adding the **same number** to both sides of an inequality:
AReverses the inequality sign.
BMakes both sides zero.
CPreserves the inequality sign.
DAlways produces an equation.
Answer & Solution
Correct answer: C. Preserves the inequality sign.
Rule 1: equal numbers may be added (or subtracted from) both sides of an inequality without affecting the sign. Only multiplication/division by a *negative* number reverses the sign.
