Symmetric+Property

=Symmetric Property=
 * If //a// = //b// then //b// = //a//**

The Symmetric Property seems obvious. However, while the Symmetric Property is true for the "=" sign, many other comparisons are not "symmetric", like inequality (greater than and less than) and "is a subset of". The Symmetric Property is useful in algebra for re-writing equations.

For example: > //x// + 3 = //y// > //y// = //x// + 3

is an example of the Symmetric Property being used to re-state an equation.
