Properties of Equality Addition Property : If a = b and c = d, then a + c = b + d. Subtraction Property: If a = b and c = d, then a – c = b – d. Multiplication Property: If a = b, then ca = cb. Division Property: If a = b and then c b c a then c = , 0 c b c a = 0 c
Substitution Property: If a = b, then either a or b may be substituted for the other in any equation or inequality. Reflexive Property: a = a Symmetric Property: If a = b, then b = a Transitive Property:
