What are the "Grammar Rules" in the Language of Algebra?

The "Grammar Rules" of Algebra: Arithmetic follows the basic "grammar rules" or properties of Algebra. The following are the names of the more well known properties [or laws].

Commutative Properties:

for Addition: A + B = B + A

for Multiplication: A x B = B x A

Associative Properties:

for Addition: A + (B + C) = (A + B) + C

for Multiplication: A(B x C) =(A x B)C

Distributive Properties:

for Addition: A(B + C) = AB + AC

for Multiplication: (A + B)C = AC + BC

Identities:

for Addition: A + 0 = A = 0 + A

for Multiplication: A x 1 = A = 1 x A

Inverses:

for Addition: for every real number A, there is a real number denoted by –A such that: A + (–A) = 0 = (–A) + A

for Multiplication: for every real number A not equal to zero, there is a real number denoted by 1/A such that: A(1/A) = 1 = (1/A)A
