[2004-08-26 23:04 UTC] frank at tuxrocks dot com

Description:
------------
When a 'difference' operator is used immediately after a 'right bracket', it throws an error. A 'sum' works, though.

Reproduce code:
---------------
$expression = "(2^3)-3";
# $expression = "(2^3)+-3"; --- this works, though
$rpn = new Math_Rpn();
$Result = $rpn->calculate($expression,'deg',false);
print_r($Result);

Expected result:
----------------
5

Actual result:
--------------
