I think the answer is yes, but I cannot be sure.

Commutativity.
If, as is normal, ab represents a times b, etc then ab + ab + cc = 2ab + c2 which is generally not the same as abc.
ab + 2
ab=1a+1b a is equal to either 0 or two, and b is equal to a
The existence of the additive inverse (of ab).
If you do not assume that "plus" is commutative, all that can be said that it is equal to A plus B.
The real answer is Bc . Hate these @
yes because ab plus bc is ac
No, AB+ people can receive blood from all blood groups.
ab x ac = ab+c, where a, b, and c are all real numbers.
No - a pos can not donate blood to a negative
Commutativity.
2ab
then the baby will be O plus, or AB plus , I think .
If, as is normal, ab represents a times b, etc then ab + ab + cc = 2ab + c2 which is generally not the same as abc.
associative property
AB pos or AB neg
