*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 .
