Thanks all!! I get it now :-)
It helped to have a number of different explanations, thanks
for taking the time to post. Much appreciated.
I generally do not expect operator precedence to be reliable at all
except for:
+ - (binary ops, not the unary)
* /
**
for other operators I would have explicit parens. It's too much work to
remember the rest of the precedence sheet.
Most programming languages don't differentiate in text between the
number "negative 3" and the expression "negated 3". APL does. The former
is written as "¯3" (3 preceded by the overscore character) and the
latter as "-3" (3 preceded by the minus sign).
