Question | Answer |
---|---|
Commutative | CO- Change order a+b = b+a d*d=d*c 5+12=12+5 |
Associative | AS- Always same... but the cheeks move (a+b)+c=a+(b+c) (c*d)*e=c*(d*e) |
Identity | ID- no one can change you a+0=a c*1=c |
Inverse | Opposite= a+(-a)= 0 c/1 * 1/c = 1 |
Distributive | Distribute a number though a parathesis. a(b+c) = ab + ac d9e-f)= de - df |
