User guide

For all single use variables, the calculator does not require a distinction
between bolded and non-bolded variables. For our purposes you may use
either bolded or non-bolded variable representations. It is noteworthy, how-
ever, that the calculator distinguishes between multiple variable expressions.
Bolded letters grouped together are implied multiplication whereas non-
bolded lettering is read as a single variable xyz.
The tab labeled ( contains a directory for all functions and calculator
commands. We will refer to this as the catalog. Using the catalog we can
access commands like absolute value abs( which treats absolute value as a
function prompting an input.
