Sometimes to avoid confusion, a
complicated
expression must be inclosed in
parentheses
( ), brackets [ ], or braces { }.
When
multiplying
quantities
containing
parentheses, brackets, or braces, you first
complete the operation required within the
parentheses (brackets or braces) and then
multiply the quantities. For example: [4 + 7
+ 2] [5 x 3] equals
[13] [15] or 13 x 15. 13 x 15 = 195.
