According to the property of symmetry of equality,if a = b then b = a.
While this seems pretty obvious, note than "greater than", for example, does not exhibit this property.

The reflexive property of equality says that anything is equal to itself. In symbols, A = A. Equality also has the symmetric property, "If A = B, then B = A", and the transitive property, "If A = B and B = C, then A = C". the previous statement is correct, however their is a proof that this theory is incorrect. I will not say it because then you will just tell your math teachers that it is your idea. Bill Door- However, that "proof" is an invalid one because it relies upon dividing by zero, which is nonsense.
distributive property of equality
symmetric
That is the commutative property of equality.
The reflexive property of equality states that any number is equal to itself. This property has no proof, as it is the fundamental building-block of all other proofs.
