ARITHMETIC OPERATIONS

                    - a
                    + a 
                    a  && b        (logical AND;  not audio-rate) 
                    a  || b        (logical OR;   not audio-rate) 
                    a  +  b
                    a  -  b 
                    a  *  b 
                    a  /  b
where the arguments a and b may be further expressions.

Arithmetic operators perform operations of change-sign (negate), don't-change-sign, logical AND logical OR, add, subtract, multiply and divide. Note that a value or an expression may fall between two of these operators, either of which could take it as its left or right argument, as in

                    a + b * c.
In such cases three rules apply:

1) * and / bind to their neighbors more strongly than + and -. Thus the above expression is taken as

                      a + (b * c),
with * taking b and c and then + taking a and b * c.

2) + and - bind more strongly than &&, which in turn is stronger than ||:

               a && b - c || d is taken as (a && (b-c)) || d
3) When both operators bind equally strongly, the operations are done left to right:
               a - b - c is taken as (a - b) - c.
Parentheses may be used as above to force particular groupings.
