Mathematica aside

In Mathematica, it is convenient to give all expressions a "name".  I try to pick ones that are consistent with what is being done (but sometimes "temp" is used).  This assignment is done with an "=" sign.  To make an equation, a "==" is used.  This distinction is very useful in computer algebra and is employed in all of the packages with which I am familiar .
