Expression Parameters

Expression parameters define a parameter in terms of other parameters. Any indicated calculations will be evaluated.

$p = 4

$q = ($p+1)2

$r= $p + $q

Given these definitions, the following equation:

$p + $q + $r

would be rendered as

4 + 25 + 29

where $q is calculated as (4+1)^2 and $r is calculated as 4 + 25.
