C minus B equals AB
associative property
An exothermic chemical reaction.
If you do not assume that "plus" is commutative, all that can be said that it is equal to A plus B.
A = 1, B = 9
a= 2, b = 3 (or vice-versa)
You could conclude that B lies between A and C.
Ab = 25 CD
yes because ab plus bc is ac
Commutativity.
The existence of the additive inverse (of ab).
associative property
the midpoint of AB.
ab=1a+1b a is equal to either 0 or two, and b is equal to a
If, as is normal, ab represents a times b, etc then ab + ab + cc = 2ab + c2 which is generally not the same as abc.
No, A+B is left as A+B AB would be A x B
ABC
NM equals 2x + 1, as stated in the question!
