Question 1

Addition Property of Equality (APE)

Answer 1

Used when you add same # to both sides of an equation

If a=b and c=d, then a+c = b+d

Question 2

Subtraction Property of Equality (SPE)

Answer 2

Used when you subtract the same # from both sides of an equation

If a=b and c=d, then a-c = b-d

Question 3

Multiplication Property of Equality (MPE)

Answer 3

Used when you multiply both sides of an equation by the same #

If a=b, then ca=cb

Question 4

Division Property of Equality (DPE)

Answer 4

Used when you divide both sides of an equation by the same #

If a=b and c does not =0, then a/c=b/c
