Q
commutative property
A
addition: a+b = b+a
multiplication: ab = bc
> > numbers switch positions
2
Q
associative
A
addition: a+(b+c) = (a+b)+c
multiplication: a(bc) = (ab)c
> > parenthesis change positions
3
Q
distributive
A
addition/multiplication: a(b+c) = ab + ac
subtraction/multiplication: a(b-c) + ab - ac
> > always uses two operations
