what are the simple laws in algebraic equations ann in perimeter and area

Commutative Law For Addition:
a + b = b + a
Commutative Law For Multiplication:
a x b = b x a
Associative Law For Addition:
(a + b) + c = a + (b + c)
Associative Law For Multiplication:
(a x b) x c = a x (b x c)
Distributive Law:
a x (b +c) = (a x b) + (a x c)
The additive inverse for a is (-a) for any constant.or variable. a + (-a) = 0
The multiplicative inverse for a is 1/a for any constant or variable. a x 1/a = 1
The identity element for addition is 0 for any constant or variable. a + 0 = a
The identity element for multiplication is 1 for any constant or variable. a x 1 = a
