Commutative | CO= change order a=b= b=a cx= dxc 5+12= 12+5 7x9= 9x7 |
Associative | as= always the same...but the cheeks move (a+b)+c = c+(b+c)(cxd)xe = ex(dxc) |
Identity | Id= no one can change you a=0=a cx1=c |
Inverse | Opposite a+(-a)=0 b/1 1/b=1 |
distributive | DIstribute a number through a parenthisis. a(b+c) = ab + ac d(e-f)= de - df |
