A*(B-B) = A*0 = 0
Expanding the left hand side, using the distributive property, A*B + A*(-B) = 0
That is, A*B and A*(-B) are additive inverses.
Next,
(A-A)*(-B) = 0*(-B) = 0
Expanding, A*(-B) + (-A)*(-B) = 0
Therefore A*(-B) and (-A)*(-B) are additive inverses
But, from above, the additive inverse of -A*B is A*B
Therefore (-A)*(-B) = A*B
It is not known when this was proven.
What else can I help you with?
If ab plus bc equals ac then ac equals ab plus bc?
yes because ab plus bc is ac
Ab plus bc equals bc plus ab what property is this?
Commutativity.
What property of equality is if ab plus cd equals ef plus cd then ab equals ef?
The existence of the additive inverse (of ab).
What is the property that says ab plus c equals ab plus ac?
associative property
If ac plus cb equals ab and ac equals cb then the point c is?
the midpoint of AB.
If you know that AB plus B equals C what is the conclusion?
C minus B equals AB
What does ab equals 1a plus 1B plus ab equal to?
ab=1a+1b a is equal to either 0 or two, and b is equal to a
How do you show that ab plus ab plus cc equals abc?
If, as is normal, ab represents a times b, etc then ab + ab + cc = 2ab + c2 which is generally not the same as abc.
Does A plus B equals AB?
No, A+B is left as A+B AB would be A x B
If AB equals 3x plus 5 and NM equals 2x plus 1 then NM equals what?
NM equals 2x + 1, as stated in the question!
A plus B equals AB plus energy is an example of?
An exothermic chemical reaction.
A plus B equals?
If you do not assume that "plus" is commutative, all that can be said that it is equal to A plus B.
