Fix typo (verb clarification) in math.rst

Browse Source 
Was: "parameter expansion takes before expressions are evaluated."
Now: "parameter expansion happens before expressions are evaluated."

I suspect the original intent was to use "takes place," but I see "happens" as less idiomatic and therefore may benefit non-English-native users.

@ -18,7 +18,7 @@ Description
By default, the output is as a float with trailing zeroes trimmed. To get a fixed representation, the ``--scale`` option can be used, including ``--scale=0`` for integer output.
Keep in mind that parameter expansion takes before expressions are evaluated. This can be very useful in order to perform calculations involving shell variables or the output of command substitutions, but it also means that parenthesis (``()``) and the asterisk (``*``) glob character have to be escaped or quoted. ``x`` can also be used to denote multiplication, but it needs to be followed by whitespace to distinguish it from hexadecimal numbers.

``math`` ignores whitespace between arguments and takes its input as multiple arguments (internally joined with a space), so ``math 2 +2`` and ``math "2 + 2"`` work the same. ``math 2 2`` is an error.
