1. Commutiative property of additiona + b = b + a
2. Commutative properg of multiplicationab= ba
3. Associative property of additiona + ( b + c ) = ( a + b ) + c
4. Associative property of multiplicationa(tu) = (abl c
5. Distributive property of multiplication over additiona ( b + c ) = a b + a c
6. Distributive properg of multiplication oversubtraction
a (b- c) = ab- ac
