The for removing parentheses:
parentheses will be preceded either by a plus sign +
or a minus sign -
- when parentheses are preceded by a plus sign + simply them,
nothing changes
- when parentheses are preceded by a minus sign - the
of the
change + to - and - to + -
use same rule with brackets
so, in your case first remove
parentheses...they are preceded by a plus sign +, you simply them
=.......now multiply ....recall +*-=-
=........now remove parentheses...they are preceded
by a plus sign +, you simply them
=.....now add all negative numbers just like they are positive and
