In an expression where many operators are present, some operators have “priority” 
over others. Operators with the same precedence level are evaluated strictly left to 
right. Grouping is used to change the way an expression is evaluated.

As an example, the expression:

    3+5*6 

Evaluates to 33 since the multiplication is performed first. It may be beneficial to use 
grouping to show which operations are performed first. Grouping is simply starting 
an expression with '(' and ending with ')'. Therefore, the expression 3+5*6 is 
equivalent to 3+(5*6). Grouping is very important if you want to override the default 
behavior and have one piece of the expression evaluated first. Therefore, to make sure 
the + is evaluated first, the expression is written as (3+5)*6, for a result of 48.
