• Properties of Equality

• Equation

• Solution

• Variable

If a = b ,

then a + c = b + c .

• Addition Property of Equality

• Subtraction Property of Equality

• Multiplication Property of Equality

If a = b ,

then a − c = b − c .

• Addition Property of Equality

• Subtraction Property of Equality

• Multiplication Property of Equality

• Division Property of Equality

If a = b, then ac = bc.

• Addition Property of Equality

• Subtraction Property of Equality

• Multiplication Property of Equality

• Division Property of Equality

If a = b ,

then a ÷ c = b ÷ c,

when c ≠ 0.

• Addition Property of Equality

• Subtraction Property of Equality

• Multiplication Property of Equality

• Division Property of Equality

If a = b , then b = a .

• Symmetric Property of Equality

• Commutative Property of Addition/Multiplication

• Associative Property of Addition/Multiplication

• Distributive Property

a + b = b + a

ab = ba

• Symmetric Property of Equality

• Commutative Property of Addition/Multiplication

• Associative Property of Addition/Multiplication

• Distributive Property

(a + b) + c = a + (b + c)

(ab)c = a(bc)
