hv: add brackets to make operator expression more readable

Browse Source 
v1-v2:
Bypass this case:
When binary arithmetic operators of different precedence (e.g. '+'
and '*') are mixed in an expression, parentheses are added to the
sub-expressions using the operator with a higher precedence.

v1:
The operator precedence rules are complicated and it is easy to make a mistake.
So add brackets to make operator expression more readable.
